Underrated game - that the team made all of this minus the fonts is wild! It feels very polished, like a real game and is off the charts for a game jam, would be great on mobile. The sound and graphics are also very appealing. My only comments are 1) as others have said, an indication of level, because the game is long enough that it can feel long - I think you can get away with not indicating it if the game is very short 2) I spammed Shift just to see what would happen, and I went through levels endlessly without achieving anything :D I know that's not the purpose of the game, but it's possible. 3) The colliders for the walls might need to be adjusted a bit, I found myself vanishing into the columns at times.
Overall awesome game!
