I coded limited resources and juvenile creatures. When creatures spawn, they have to wait 15 seconds until they can mate (so they don’t start mating right out of the womb like last time), and now when food is eaten, it regrows after 7 seconds. I’ll probably add more genes next time, or maybe even expand the map and add new biomes and plants (which would be really easy because I can just drag the food scene onto any plant and the plant now has fruits that grow and regrow).
