Fun, fun concept, would benefit from having a more zoomed out camera (and by placing said camera more towards the right of the character since it can be kind of difficult to see what's in front of the player when going super fast!
Would love to have visual and audio feedback when the clock gets low too, i personally kept dying to time without realizing it for the first few levels because there was actually a clock you had to keep track off :>)
(totally my fault for not reading the page's description though lol)
Art is cute, controls are clean, and overall it's a fun game !
Well done >:D
