You can use the arrow keys or the mouse. I actually fixed the ground. If squish doesn't show up immediately, wait a few seconds. It's like that because it would appear too early and drop to the bottom. Everything works better with a faster device. Please tell me if you find any other glitches. Not exactly hard, but it's still fun! You can complete the platformer both on mobile and desktop. It's mostly glitchless, although if your computer is slow (like mine), the squish STILL can fall through the floor! :c
Thanks to @ABitBrighter for the original project, including the squish and the levels. I actually fixed the ground so you can complete the game. *Cheers* You can also do mobile even though I've never played on a device other than a computer AND never coded a mobile platformer (or a platformer in general)!!! Working on: Secret levels :) One year anyway, I'm working on other projects at the moment though.
