I know these are harsh... but they're honest
Big issues:
-Movement
-A and D are swapped
-W doesn't even work
-There's no build-up or slow down to the max movement, just one speed
-Hitboxes are janky (e.x. Jumping on enemies and you dying, randomly nothing happening when you touch enemies, etc.)
-I somehow clipped through the invisible wall BY MISTAKE and ended up in a soft lock
-Pausing requires being out of fullscreen
-Unknown function of hearts and coins
-Counters are hidden
-The timer (I think) is currently stuck at -4
Nitpicks:
-The character is just a ball with abnormal animations
-Music gets annoying quickly
