This is an impressive project for 96 hours! I enjoyed the variety of levels and the lush art design. I do have a few pieces of criticism though, which I hope will be helpful (though keep in mind this is only my opinion!):

- The controls felt a little clunky at times. I think the main issue is that the player moves too fast, which made segments where you have to jump between thin platforms frustrating.

- In one of the levels, I kept falling down and activating the first checkpoint, overriding the checkpoint I had reached higher up and forcing me to climb all the way back up the level to try again. I don't blame you for this one - my game does it too! - but it's an easy oversight to make, so I thought it would be good to let you know.

- I think the "repairing checkpoints" system is flawed. Because you lose bolts upon death, which will potentially prevent you from activating future checkpoints, this system punishes players who die more often, despite those players being the ones who need checkpoints the most. Luckily, because there are so many bolts in the levels, and because you don't lose many on death, this shouldn't ever become an issue for anyone, but it's something to keep in mind.

- I found the last level quite frustrating due to the relative lack of checkpoints and precise jumps.

- This one's just me being confused, but are you supposed to be able to keep "repairing" the observatory at the end forever? The animation kept playing but my bolts weren't going down and nothing else seemed to be happening, so I just left the level.

Good work on this overall, though! I had a good time playing it, and it has a larger scope than I might expect for a game jam game.

I wanna try the game but the game keeps freezing around the double jump tutorial sign :(
From what I've seen though, the atmosphere is great, as are the controls, and I trust the other comments that this is a great game!

One of the better feeling platformers I have played in a jam (and I have played a LOT of them). 

Great job on the visuals, too!

Super tight controls, very nice presentation and storytelling, great job! :)

Wow, the art looks great, and the controls are tight well done!

What an amazing narrative storytelling through visuals. Gorgeous art direction. Appreciate the very fluid platforming feeling, got me hooked longer than what I intended to play. Great job on this one. :)

Love the style and mechanics ! Thanks for giving the double jump right away !!

The controls are really fluid and satisfying, the world art and level design is so good -- very polished, well done!

I really like the artstyle and gameplay!  I also liked the story telling too!  Awesome game!

Gorgeous artstyle! The platforming was also really fun and I like the interpretation of "scale" as climb!

This was really well polished! I'm not good a platformers so I couldn't make it all the way through, but I love the mechanic of finding the spare parts to repair checkpoints for the extra challenge. The artwork, the animations, the music and ambiance. It is all so well crafted. Great job!

I’m a great fan of platformers and let me tell you this one is really satisfying to play through, you nailed movement and this is not easy to nail on platformers, I specially like the wall grabbing mechanic. I also appreciate the tip at the launchpads, where you hint we can just walk into them to save the first jump!

The answer must lie in the observatory!

Impressive game for 4 days and I loved the visuals!

I would have loved to explore the game but sadly I also have the bug at the sign :( looks and feels nice though

I kept getting a bug where when I double jumped at the sign that tells the player they can double jump, the game freezes and I have to close the browser. I looks like a really cute game and the gameplay feels really smooth but I wasn't able to get very far.

Tried it three times and the game froze each time. Only at the sign talking about double jumping. I could jump lots of times everywhere else though. 

I like the aesthetics of your game, both cozy and postapocalyptic! The signs and comments were also so cool, especially about the sock market :D

The way the character moves, runs and jumps feels so satisfying. I would love to play to the end, but some parts were unfortunately a bit difficult for me. I would be happy to have checkpoints after the hardest parts, as sometimes you were to make lots of hard jumps in a row but the next checkpoint was a bit too far. I also noticed that I get to some flags but later they looked like I haven't visited them yet. Do they reset after a while?

Very cool experience!

Wow, very good style and atmosphere! The controls are also great.

Very pretty and polished experience, can't really fault this in any way. Too bad I'm no good at this kind of game, I wanted to see the end!
