Thanks,🙂

I tend to use 60fps in pico-8 by default, as it helps smooth out the chunky low-res motion and stuttering. I realized the original game was 30fps and tried to switch to that, but even with tweaking values, everything felt sluggish, so I just stuck with 60.

Oh, okay, I thought you meant commented, long-form code. Here's a link to the code from the cart. I'm especially proud of the combined map decompression/autotiling system in about 100 chars at the beginning. ;)

Thanks,

There's actually no separate source code, as I code all my tiny projects in compressed form by hand. I guess that's terrible practice, but I'm not a software dev, and it lets me better monitor and control the size.

I'd be happy to answer any questions or explain things if the code's too cryptic, though.

Thank you, I'm flattered.😊

When I was little kid, I remember my oldest brother slowly typing in lengthy programs from magazines on our old computer, usually to be rather underwhelmed with a primitive game that held our attention for a few minutes. Guess I'm fascinated by the idea of fitting something surprising and complex inside a tiny space.

Uploaded a new version, managed to fix some of the wall jump inconsistencies and made the destructible blocks look (very slightly) different.

I agree it's a bit unpolished in some spots. I'm hoping to make a more fully fleshed-out version sometime that adds and refines a lot of things. As it is, I had to cram like crazy to fit the whole thing in 1 kilobyte.  That's less than 1% the size of the original NES Metroid. Those are good points, though, I'll see if I can free up enough space to tweak them.

You should be able to go down at the same screen where you start climbing to reach the double jump, then head left and jump over the barrier you couldn't before.

As always, thank you for being a kind and gracious host. =)

I found a hybrid system for the map that seems to work pretty well: deliberate design elements laid on top of procedural generation. I'm calling the little robot K5, as it's the last part of his serial number.  Initially was going to call him Gizmo, but it didn't really fit with the more realistic tone I was going for. Speaking of naming, my initial name for the game was MapDroid, do you think that's a bit too on-the-nose for a non-size-restricted version?

As for the power cell, I believe only 2 are truly hidden, I'd recommend searching the depths of the red crystal area, or around the waterfall. ;)

Thank you! I've never heard of that game before, I'll have to check it out. Also haven't encountered that glitch before or heard about it from others, though as some of the logic is a bit hacky, that's not too surprising. I'll see if I can replicate it and figure out what's happening.

This is a legitimately fun, cool little game. Nice job! As the fellow maker of a game with a googly-eyed colored-sphere protagonist, I approve of your easy-to-animate strategy ;)

Thank you very much, that's high praise coming from someone with your coding savvy.

There's definitely some procedural generation smoke and mirrors, but it's a video game, what it looks like is kinda the whole thing. Glad to hear people are legitimately liking how the game plays. It's my first-ever shot at a Metroidvania, so that's encouraging for potential future projects.

Thank you, glad to hear you're enjoying it!

I might have to shatter the illusion a bit, but there's actually not very much map detail stored. The world is made up of just 35 rectangle and oval shapes drawn to the screen and copied to map memory. The trick is that the shapes are drawn over 64 cel-like room shapes composed of several hundred randomly-drawn black rectangles. I hit on this after initially trying pure procedural generation, which was too chaotic. Combining random detail with specifically-designed features seems to give most of the effect of storing a lot more information, though you have to work with what's there. It's kinda like looking for faces on a textured ceiling. =)

Thank you, looks like you got a good time! I would have liked to include at least some sound effects, but even that would have eaten up space fast.  I'd like to make a more fleshed-out, non-size-limited version of this at some point, I just have to work at limiting my scope (a big reason I started size-coding in the first place).

Oh also, they're technically power cells (yeah, I know they're squares, but Metroid gets away with it. ; )

I'm glad you enjoyed it. I have to say my intention wasn't to be evil, more that I only had 12 total collectibles, and if I handed them all out in a straightforward way, the game would basically have zero longevity or replayability. If i'd really wanted to be evil, I could have included some blind pitfalls (including ones  of that drop you out of the whole map), or made pits you could fall down and not get out of. =P Also, while the destructible walls aren't marked, they don't have any crystals on them, as you can't destroy those.

What you're saying about the double jump (or as I like to think of it, 'jump jets') makes sense. I didn't have any space for explanation (I mean, the game's title doubles as an explanation of your objective) but I had hoped the deep pit you have to climb out of in the green quadrant would help players come to grips with it.

Thank you, having the game stand on its own merits regardless of file size was my goal. I'm realizing the time in seconds is pretty awkward, but couldn't fit proper formatting. As it is, the title logo and time display are part of the same print command. And yes, they are green squares, they're supposed to be metroid-style power cells. =P

Glad you liked it enough to finish! My goal was to make a decent small game, even if not considering the file size. Sorry about the time in seconds, proper minute: second formatting would have eaten up way too many bytes. o_O

Nice job on the graphics and sound, and coming up with smart simplifications! The 97 seconds remaining submission is kind of the cherry on top. =) Was thinking about a demake of Dig-Dug or Frogger, and had made a little test, but my project took too much time for that. Glad to see somebody made one.

Thanks, 

I've just been practicing the digital equivalent of jumping up and down on a suitcase to cram 'em in as tight as they'll go. ;) This one was tricky. I had a good base from my last entry, but as I've found when encoding sprite and map data in custom, highly-compressed form, things can get very temperamental.

Thanks for letting me know about the glitch, didn't have a lot of time for playtesting. I uploaded a fixed version. It appears I had failed to update a number from 21 to 22...

I can very much relate, it's both an interesting puzzle and an extreme means of scope limitation. I get game ideas, but see the potential for something beyond my current skills and don't know where to start. Moving forward, my strategy for any more substantial projects will be to make a small, simple version first, then a slightly scaled-back version after I've gained the initial know-how.

I can sympathize with having to hack things down. Personally I think one of the best things about cramming code like this is that it forces you to find efficient ways of doing things, and you can use that in other projects that aren't so constrained. I'm planning to make a non-crunched version of my entry sometime after the jam, to further polish it up and flesh out some of the ideas.

You're on a hot streak! Great job getting so many subsystems working, I'll definitely have to pick this one apart and learn from it.

Particle effects, I like the ambition! Was planning to make a racing game as my second entry, but my current one is demanding actual world design and I've never made a game of its type before. Sometimes I wonder why I make things so hard for myself, but I guess that's kind of the nature of size coding. 😛

Even more impressive than your usual excellent work! At first I was afraid any mistakes would send me off the edge, pleasantly surprised to just be slowed down. Also, great job fitting some sfx in there!

Always glad to share a little hack or two. 😉

Great job on the animation! Read your comment about ninja stars and the ctrl-f glyph to mind, so altered a couple lines of code and changed the balls to stars. Here's a link (1024 compressed bytes):

Nicely done fitting both a solid raycasting engine and an easy-to-use editor in a kilobyte. One little nitpick is that the stars should probably move less than the moon since they're further away, but otherwise, good job.

Yeah, there's no substitute for good tactile feedback. One of the reasons I've never been a big mobile game player. Glad you enjoyed it, though!

The little 6 is a single-character substitute for "\^", which is a common control code. Zep didn't necessarily make all the shortcuts like that very obvious. I actually included characters 0-15 in the tool, they're just in the code as comments and you can copy and paste them, since they're not printable in a running program.

Okay, that makes sense. I've been working on a number-based puzzle game and it's so open-ended I don't know how to check if things are solvable, so I've started chipping away at brute-force testing.

Well, I actually don't have a less-minified version, as I usually code my small projects directly in condensed form. I can give you some info on how things work, though. There's a string at the beginning:, ?"⁶1⁶c6⁶!5f10+⬅️5✽●6⌂3", which activates the secret palette colors. Basically, the question mark is a condensed print command, '⁶1⁶c6" replaces the flip() and cls() commands, and "⁶!5f10" functions as a poke command to hex address 5f10. The symbols that follow are the values that colors 0,1,2,3.... are assigned. The bezel is drawn using the reversed shape feature in Pico-8 0.2.6, which is activated here by another poke command in a string. If you haven't, I'd recommend looking up and reading about P8SCII control codes, which can do all kinds of useful things in a small space. Some of the required symbols are tricky to print out, so I made a little tool that makes that part easy, you can find it here: https://www.lexaloffle.com/bbs/?tid=40525

Nice core mechanics and very slick effects! I did come across a bug, in that I left my paddle in the center and it somehow never missed the ball, it just kept endlessly scoring.

Surprisingly complex mechanics, awesome work. Was going to ask how you tested if all the puzzles were solvable, but looks like you pit a little disclaimer in there.😄

I'll have to dig into this one myself, nice work!

Again, thanks. Glad you're enjoying it. I've had ideas for LCD-themed projects for a while. I've spent time trying to overcome the limits of Pico-8's low resolution to build worlds that seem large and open, so it's neat to see what's possible when going the other direction and depicting something small and close. I'm thinking I might try and simulate a bit of motion blur next time.😉

Thanks=),

I use my little character printer tool.  https://www.lexaloffle.com/bbs/?tid=40525

For most chars, you can just use the dpad and buttons to build strings, though for 0-15 you'll need to copy them from comments in the code.

Well, if you'd like to adjust something, there is an easy way to free up a few characters. After ::_::, print the string ?'⁶1⁶c', this will replace cls() and flip(). Got that one from a tweet by zep.

Plays well, and has probably the most entertaining one-sentence synopsis I've ever read. I think making the hearts a little less scarce would help, but otherwise great job!

Thanks,

I made a tweetcart version of snake some time ago, and I figued this gave me enough room to fancy it up a little. Glad you like it!

Yeah, the dungeon does rely pretty heavily on trial-and-error since there wasn't space for complex mechanics, and storing two copies of one sprite and using tile properties was cheap. The entire map is shown for a frame at startup when it's being drawn, so your cheating isn't entirely unprecedented. Glad you had fun, and thanks for the feedback!

Okay, a fixed version is up. The offending area is now blocked off, though still visible for the sake of intrigue ;). The cave entrance is also slightly repositioned, but still on the same screen.
