Really nice game! I was looking for a simple ,fun 2D Game and came across this one - I really enjoyed it. Played tournament mode and it's definitely challenging , but I'm  determined to beat it soon . In single race mode I noticed that one match showed me second even though I finished first . Besides that I didn't encountered any other bugs.

suggestion : Adding a elimination mode could be a fun addition .And also please bind WASD keys .  Hope you consider it ! 

Good luck on this and future projects !
