MaKey MaKey - Whack a Mole
You can play with arrow keys (left, down and right), but the best is to play it with a makey makey, for example I use a spoon as a hammer to hit 3 iron sponges, but the possibilities are limitless!
I made an halloween version much easier to remix, have a look!
Share in the comments how you enjoy it and have fun!
I adapted an awesome game by @toontownmiser, reducing the number of moles and switching to keyboard control (instead of mouse), in order to use it with a makey makey.
