The jump and speed are completely unbalanced, so the challenge is to don't get out of bounds! I think the idea was completely different, but it still was a game.

I think level 2 > level 4 > level 1 > level 3, because you can just skip level 3 jumping it, but you have borders so you don't fall, different from level 1. On level 4 you have a city, and you need a perfect timing in level 2.

Seemed a little unfinished, you can just spam the jump key and get out of bounds extremely easy and there's no real way to reset. Feels like the player is running on ice and constantly accelerating if you hold the key down. It has a really good basic concept, that if you spent some more time working at it, has real potential.
