Dude, seriously awesome game! The racing mechanics are so good, and the way you implemented the theme - GENIUS! I managed to beat every single level (including the bonus one). If anything, I just wish there were more levels haha
I did notice a bit of a bug, although I think someone else already posted about it. If you spam the polarization button, you aren't effected by the magnetic zones. It's not really a bug I even think NEEDS to be fixed, since all it does is prevent you from messing up in the magnetic zones, but it did help me significantly on the bonus level.
Anyway, AMAZING job dude! I think this might be my personal favorite game in the jam so far. It's that good.
I think you may have already played and rated my game, but if you haven't already, please give it a try! :)
