My old Mega account got hacked at some point, so I removed the old links - but it's sorted now, so here's a reupload:

I also added all of the Community Characters here, as I don't think that tab will be available on the Steam version due to copyrighted characters. Hopefully these versions will carry over for v1.0.
In all, there are about 60 dev-made characters, and about 120 I made myself - plus all of the characters are saved as pngs so you can check out their looks before downloading. Hope y'all enjoy.
