From the games of this jam, this is one of my favorites so far. You did a great job, especially the levels are really well done! Animations are cool, the menu is also looking fine.

There are only two things you need to improve in my opinion: First, add a few environmental details to the levels so that the player has some help for orientation when trying to memorize where the spikes are. It does not have to be much! And second, change the color of the movable objects so the player knows right away that it can be interacted with. Apart from that ... keep going, you did well!

okay, good stuff first: The level design is really good, and the level of polish is unreal. Its very fun, suits the theme very well, and the puzzles are nice and challenging.

Now for the criticism:

In the second room, i spent about 2 minutes trying to figure out what the heck I'm supposed to do, until I accidently pushed the big box and realized that's what I'm supposed to be doing. the fact that it shows the controls at the beginning is great, but a bit of briefing on the mechanics would have also helped. Even just a few visual cues like a specific color means that an object is interactable would help a lot. 

The disappearing spikes are really punishing. You might be able to put your cursor somewhere to keep track of 1, but after that its just guessing, and randomly guessing distance while also being sent back to the start if you guess one wrong just isn't that fun.

The boxes that you need to move are really slow, I keep holding down left or right for 5 eternities and it ends up moving 2 cm. Just make it a tiny bit slower than the player.

There are 2 animations: Idle and Moving. There are no pushing animations, going into a door animations, or even jumping animations. The character feels a little stiff with just 2 animations, and pushing the boxes also look really weird.

The game is kinda devoid of sound. There's a jumping sound and thats it. If you were going for a kind of barren vibe, then there's ways to add more sounds without killing the vibe.

Theres no win screen. when you get trapped in the thing in the final level or go through the door then it justs kicks you back to the title screen, which feels a bit weird.

Conclusion: Most of these criticisms are just nitpicks in an otherwise really good game. Combine this with the fact that this was made in 48 hours AND this is a beginner jam, an you got one of the best games in the jam. My overall score is 5/5.

Nice level desing! also the art is superB for a 48h and only one person. GJ!

Very nice game! My only real problem with this game is the lack of music to set the theme. But other than that, the levels are well designed and the art is simple but effective! Good job!

I think the levels are very well thought. Nice game!
