It was actually a pretty fun game, and if I recall correctly, eventually free. You might actually be able to find it online somewhere.
Although I’m not entirely sure if you wanna call it a game, per se… It was more like an evolution engine wherewith you got to experiment with different traits combinations, and eventually end up with an evolved creature of sorts. Interesting and amusing.
It seemed like something one might find in a fifth grade biology class as a teaching tool. But fun!
