CVG's birthday is April 27th? That's cool, must have been meant to be for me to be a member, lol.
As for characters, they can be original creations FOR SURE!
Make sure all entries are submitted in this thread in form of a sprite image or animation and character info (name, creators, etc.)
Then send me the character download link via PM so I can test them out and whatnot.
Just a reminder, all submitted chars will be hosted in the CVG charcter downloads section after the contest has run it's course.
Good luck with your chars!!!
