Nice work! I had fun, very much enjoyed the concept and the pixel art. The scaling mechanic and controls could be more polished as I managed to get myself into a lot of weird states by scaling up too fast. I hope you continue making games as it's promising considering this is your first!

Good job! The idea is there and I like the mechanics. The pixel art was pretty good and so were the player sprites but the style was inconsistent and they end up clashing, the player wasn't pixelated while everything else was. For a game jam game made in a short time limit, this is perfectly fine, and especially considering this is your first game. My first game was way worse, good job! Hope you keep making games!

Good attempt for a first game! Some pointers:
- Some of the controls were a bit finnicky (mainly the potions, perhaps change it into a wand ?)
- There was only one instance of it, but the box pushing physics seem to be a bit odd
- Instead of allowing the blocks to be walked through, just kill the player to reduce the amount of time spent going back

Aside from that though, great effort-- lots of SOUL! 
If you have the time, we'd appreciate if you also took a looksy at our game < 3

Impressive work for a first game!! It is a very fun idea that you should expand in the future :)

In case it helps, I would suggest leaving more empty space in the levels, specially in the first ones, where you want the player to perform jumps easily (without hitting the ceiling) and get used to the mechanics of the game. Also, if you keep only a few scales (say 0.5, 1, and 1.5, instead of steps of 0.1), you probably don't need the labels indicating scales, since it would be obvious from the size of the character and the objects. It feels more natural if you can convey an idea using graphics or storytelling rather than explicitly telling the player about it. Keep it up and congrats again! :D

Others have already said a lot of the points that could be polished, one thing I will comment is that the walking through walls when small could perhaps be demonstrated better by having some kind of tunnel looking asset. Anyway congrats on your first game, it's very impressed as a first game in only 4 days, hope you enjoyed making it and continue to do so!

Pretty solid for a first game, congratulation ! I had some difficulties with the inputs, spacebar to jump would be more intuitive, other than that the music is great and the game has cool vibes!

Thank you for the treat! The music really got me the very first second. And the level is relaxing, taking me to the flow easily!

I guess the controller and guidance can be polished better ( like in my work lol ).

Hope this get seen and played by more players!

Congratulations on making your first game! I think other people with better knowledge of platformers game design have already covered how to make the controls feel better, but I had a few other pieces of feedback: 

1) I think for future games, you might want to consider making the instructions just be in their own box instead of in the world, since with this setup, often I couldn't actually read them fully until I was far enough along that they weren't particularly helpful anymore.

2) I suspect you're using an AZERTY keyboard to develop? That threw me for a loop, because I'm used to game instructions assuming you have a QWERTY keyboard, so usually the controls are labeled as WASD.

I hope you keep making more games after this jam!

nice little game, i pretty much had a similar experience as the other commentors so i feels like i dont need to reiterate, but great job finishing a game ૮₍´˶• . • ⑅ ₎ა

Didn't expect the possibility of walking into the wall to get out of a hole haha. I think I glitched at the end?? I didn't know if I was supposed to try and change the slime's scale (it didn't, it  just popped out of existance at one point after spamming my potions to no result) and when trying to jump over to the I think final box I fell on the spikes, but got the text of having gotten the book of knowledge as if I had won.

Congrats on your first game!

Some specific things about the controls (as others have already generally mentioned), you want to aim for them to feel intentional and snappy. Getting good platformer controls can take a lot of tweaking or prior knowledge. There feels like a slight lag from when the player presses the jump button to when they actually jump, and the momentum of the forward motion is continuing during this time, which would lead to me falling off the edge without ever jumping. This disconnect feels frustrating and like it's not my fault, but the game's fault (a game can be difficult/frustrating and still feel fair). You could consider giving a few frames of wiggle room after the player has left the platform to still register the jump. You can look into GMTK's own video on Celeste to get some other ideas.

Also I think it's quite common for space to be the jump button. You could have both w/z and the space button  be jump and leave it up to the preference of the player.

It's also worth considering the intention of the level design. The first level is fairly simple in design, but not simple to play though. The jumps between the platforms are difficult because of the low ceiling and the fast forward movement of the character, mixed with the low friction with the ground. If the intention is to teach the player about shrinking to get through the smaller corridor, then just do that, and just once.

Good game ideas though, which fit the theme nicely. I also liked the art and that you added a bit of story.

I had similar issue as others with controls and collisions, but I appreciate you took that into account and just allowed out of bounds movement. I think as a proof of concept its impressive, and with some polish could be really fun!

But as far game jams go, you did good and should be proud of what you made!

Very nice game jam submission! I like visuals and mages design. Godot typically has issues with colliders and I fell once out of bounds. For some reason, button for resuming didn't work and the other time i couldn't skip story to the game. Also for some reason in tutorial it said that controls are Q, D, Z instead of A, D, W. I liked the game though. Good work!

Nice little game! Controls could be better but besides that good job!

Good game. The player control is a bit weird. It would be great if there was a coyote time feature available for the jump mechanics.

The game looks nice, the art style and music are very coherent and fit well. It can be a bit janky, like when I died after getting past a big spike but got the end screen instead of being able to restart the level. Pushing the box was also a bit buggy. But beyond that, it's quite enjoyable. I like that there is some story to it. Keep up the good work!

Overall not bad, but that big spike has a square collider instead of a triangular one, which is a little annoying.

It is a good progress for game development. However, if evaluated as a game, it wouldn't be fun for normal players. To solve this, you would need more experience making games; it is normal when it's one of your first projects. And I recommend imagining the whole game from start to finish and determine every detail that produces that result. This way you can God willing make sure that reality matches your vision.

Really fun little game, super solid first game project! The controls were a little unorthodox, kinda all over the keyboard, but overall, nice job!

Very decent!
