NinjAh! is a pixelart arcade game for mobile phones, inspired by a minigame featured in an old Commodore 64 title. The player must defend himself with a shield from unilkely objects hurled against him, at different speed and height.

The game features different levels, each of which introduces a new gameplay mechanic.

The goal of the game is to resist as long as possibile without being hit to unlock all the levels and many different alternative characters.
