Congrats on your first game jam! That song is grooving! Gameplay is pretty simple but mostly decent. A third level would be nice, you know, rule of three, but I'm sure that's a time thing. The maze has that classic Unity collision problem where the character gets stuck on the wall they're trying to walk along so you have to zig-zag off the walls. I don't know how to fix that but I'm sure there's a way. Graphics were super basic. I won't knock some classic cube-on-cube action, but it could go a lot further to distinguish itself. 

But hey, the most important thing is you made a game, no matter how small or how basic, and you got it out for people to see. Congratulations, and keep at it.
