I have created my first 2.0 level! Yay! Thank you, thank you, you are too kind. Anyways, I made this bad level because I wanted a level where you could play as any character and still beat it, it's supposed to be hard, but I think I just made it a bit annoying and bad, so excuse my level design. I did make a custom boss, and you CAN cheese it, but I'm not telling you how for obvious reasons, and- yeah basically you get the point, this is bad. Please take it with a grain of salt.
Cave Story spoilers! Probably don't need this, the game is from 2004, but still, SPOILERS!
