TigerCake is going to be some form of abstract styled first person shooter. May include some humor, so things aren't too serious.
Thought player could collect keys in the levels to get access to locked areas. They come in 3 shapes and 3 colors. Initially I intended the Gear Key to be Blue, Skeleton Key to be Yellow and KeyCard to be Red. So no idea if I'll go with that idea or mix it all.
Also trying some floating islands. I think it's easier to surround the outdoor areas with sky than lavapits or really tall walls.
