I had this really strange game called Seventh Cross Evolution. It wasn't really a good game, but I loved it.
You started out as a tiny amoeba, and ate food to gain evolution points. You'd then use those points to add colors to a grid, I think you had six colors. The arrangement of those colors in the grid would unlock new body parts, like tentacle legs, or human arms, or a shark head.
It was super weird and clunky, but I loved it as a kid. I would spend hours just making pictures and seeing what I'd get. Might have to revisit that one soon, could make a fun stream game.
