This game is actually pretty neat. The idea is very good and the execution feels just like that fast-paced, goofy speedrunning game you come across every so often.
Though, not sure if it's a lack of refinement or a skill issue, but I found myself rage-quitting at stage 5 (the one with the dash fish) because I kept falling off the map (for some 30 attempts). Would definitely give it a shot again if I have some more time!
