Wow, really well made!
I like the music very much, the gameplay is great. Creative idea.
The only thing that makes me sad, is that if i'm diagonally moving, i can't jump. Maybe a bit harsh that i die from just touching the walls
Could benefint from a quicker restart so i don't have to always move forward to press e to retry.
Maybe a bit unintuitive that you can buy stuff, might improve things (for ppl like me who didn't try going upwards for a long time) if you stated in the description, because it is only shown on one of the screenshots.
This is a very well made and polished game, which held my attention for quite a long time, and deserves more attention :)
Also I think the game broke a bit, after failing the blue level. i failed, then went again, then the game gave me tickets for completing the level which i didn't do, then multiple music started playing simultaneously. Essentially one of the levels kept on going while not in game, granting me tickets for free
