Thanks! Sorry about that being stuck part, for some reason the jump height isn't consistent across all computers. :c couldn't fix it on time. But thank you for playing the game!
Could be some frame related issue, when I started the game it felt like it jumped too fast, if you happen to create a version with some bugs fixed I could give it another try.
UPDATE: I tried on another browser (chrome) and works better, maybe it has locked fps or something.
