I spent yesterday making a Simon Says / Simon game for the Arduboy.
The game is simple. Remember and repeat the sequences as they show on screen. There are twenty levels generated randomly, so the game should be replayable. The random generation isn't quite working perfectly, sometimes sequences repeat through the same levels (ie, level 1 is almost always Left then Right).
The code is a little spaghetti, but it would be my first major attempt at a game written on an Arduino platform.
The game can be found here: https://github.com/Slade1972/Arduboy-Says
I hope people enjoy the game. It was a good challenge making it.
