Remix and read the comments in the first sprite ("README") I WILL NOT BE ADDING ANY CHARACTERS UNLESS THEY FOLLOW THE FORMATTING AND INCLUDE SOUNDS. (You are limited to submitting 3 characters per person) If you'd like, you can add your own Easter egg (just create a new sprite called "easter egg") and create a comment explaining how to get it and what it does. This is not required and frankly, there is a good chance that it won't even get added into the game because if I have all 70 submissions asking for an Easter egg, it would be pointless to add every single one of them.
You will be credited for your contribution. (Please don't remix without adding anything or without following the format! It's really inconvenient for both you and me.)
