This game is still in Early Access, but I've been watching some game play on youtube. Very simple graphics and straighforward gameplay, but it seems to be the sort of thing that I could easily waste away hours playing, and even just watching this YouTuber play I feel I get very invested in the individual characters.

Basically, you start off with a male and female creature. You have to collect food to have the energy to make moves, breed your creatures, find new creatures to expand your genetic diversity, fight off carnivores etc. It's reasonably involved and your characters carry dominant and recessive traits which means you can't just breed anyone together. Plus you can get some pretty cute variations.

Check out some game play from the early build back in August. I think it's released next year. It looks like a fun
