Game

Choko Loco 2

A fairly linear action adventure game where you collect spam, extra lives and fight lovecraftian monsters. There is some exploration but it's more of an action game. I consider it of the "psychological horror" genre. It is also a 3d platformer, like Mario 64 but insanely twisted. You can also swim underwater, and you will have to to finish the game. There are other environmental hazards such as mud and slime.
