Super cool right? And if you wish, you can put borders around the game! Let me know if you have pixel art you want to use as borders - the vanilla Goomba Color only adds borders around known games (it has a database). You have to code a bit to add your own... Maybe I'll make a tool for it, seems like a big oversight.
Update: Great job on the game, actually, I finished it and love very bit of it ;)
