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.
