The controls feel good and are really great with the animation and sound effects! (Except when the bug kicks in, but that’s no problem in a game jam like this, because we can just reload the game.) The sliding effect when turning feels great! I like the concept, and it got me hooked enough trying to get a perfect score, which isn’t easy.
I didn’t know that the order of the flags matter, so I though it was a bug when nothing happened when I reached a flag. Some number indication on the flags would help (or maybe don’t care about the order, letting the player decide.)
I like that you have mobile control support as well as keyboard support for PC gamers. Maybe you also have controller support, which would really suit this game.
It was a bit difficult to understand the difference between “menu” mode and “play”-mode, because the UI looks almost identical. The music changes, which is a good indicator that something is different, but I think some extra UI changes would make it even more obvious.
These minor critiques aside, I really enjoyed this game. I think it can be released after fixing the bugs and giving the game some more love from you guys, to make it even better. Adding more levels, and maybe a few extra game elements (e.g. add a power up to slow down time,) and you have yourself a complete game ready for release. Good job.
