Well done. First I ran to the right and just fell endlessly, probably something that should be prevented. Esc or restart did not work for me. I am glad I gave it another try, it is a solid platformer mechanic. Configurable controls would be great, on my keyboard it was very hard to play. The wall jump mechanic could feel better, I was hitting space a lot and did not find a smooth way to reliably climb up the walls. The art style is very cool and fits the theme and the game well.
