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.
I had that game! It was so weird! Cool concept but I never had any idea what I was doing. The DNA sequence minigame (?) was neat but it was never clear how you get any specific results. I wonder if there's just an RNG behind it and none of your actions really mattered.
I got to the gold man level (which I guess is the pique of evolution and the end stage) and the game didn't really end. I just was able to walk around slapping animals and taking almost no damage.
I picked it up again used and threw it in my dreamcast and couldn't get through it. I found it tedious and kind if dull. Would be interested in seeing a remake though- I bet modern engines could do a solid job with some of the ideas in it.
