Ahhh, the monstrosity. Press space for reasons, use wasd to move the cat, move the mouse pointer and click for a different effect. Good luck, don't die, and if you're feeling crazy there are some disconnected blocks inside you can reconnect. Also check out my sick gravity script, I made it a while back but I figured why not use it here.
I did this, mine, me, a little bit of help in the form of inspiration for sounds to use from Cooper, but other than that, just me.
