TigerCake is going to be some form of abstract styled first person shooter. May include some humor, so things aren't too serious.
Primary fire: fires 8 shurikens. Alt fire: fires a bomb with mini shurikens inside. The mini shurikens are fired toward nearby enemies. But be careful, they hurt if they accidently hit you. Primary fire mode is safe at close range...
Earlier I had a double barreled shotgun for this purpose, but I thought that looked too ordinary.
