Great game, I was gobsmacked by how many levels you managed to make in such a short amount of time, that's amazing! I had a lot of fun playing as well :) The audio went well with the graphics although I think the footsteps felt louder than the music so I turned down SFX in the settings and music up.
I can't remember if games usually have the Retry button first and then Next Level after (when you finish a level) but I kept wanting to press the first button automatically before realising it should be the middle button. Maybe that's just me being weird :)
Well done on making such a polished game!
