This is a weird one...You might be asking what this has to do with Battletoads. But, spilling the beans here, not much. Something I did when I starting making games 5 years ago is rip assets from NES games and "glitch them out." So I thought I'd do that again, use that as a springboard to some real madness this time!

Game uses keyboard & mouse. And figuring out what to do is precisely how you are supposed to play! I don't want to reveal any of the surprises here!
Have fun and lemme know your thoughts...
