Arrow Keys, Space WASD, Z Another Short thing, but with Co-op! Arrow Keys for Benjiro, and WASD for Mateo. They both can use the Fire powerup, and you can use 1 to give them the power. It's still in progress, but it's the best I have for now. But Yeah! You can remix and replace me with your oc and such, or even if your a wiz and understand my nonsense you could actually change the map, or you can change the music if ya want I don't mind.
Original project by @BXWash I decided to see what I could do, now the characters automatically run after walking for a bit. For some reason Mateo isn't able to give both players the fire ability when they hit the ? Box.
