I made "How fast?" multiplayer game version on IchigoJam and Wii U. (original "How fast?" is in mini games)
1. Players are ready to push a key on keyboard
2. RUN to start a game
3. Push your key quickly when LED turnes on
4. Show a winner
This is SMILE BASIC on Wii U (プチコンBIG) version using max 4 Wii Remote controllers.
