I like it, already built a diverse world with various land masses and zones. Just wish that there was a bit more you could do. More biomes, more terrain types, etc... Of course, I know it's still in development, and that more features are planned, which I'm excited for. Also, the animals, they all seem the same to me, and how they work is rather unbalanced. Prey species stand no chance once a predator gets amongst them. Any predator can pretty much kill any prey, then reproduce! A bit too easy for large herds to get wiped out, which in turn leads to the predators extinction due to famine. What it should be is predators only hunt some of the time. Once 2 predators have eaten, then they can reproduce with each other, at which point they may stick with each other as a pack, troop, herd, pride, whatever. Or maybe they won't, you could have certain species that reproduce then go their separate ways. Increasing their spread, but slightly decreasing chance of survival. Also, different types of prey should have different characteristics. Maybe the bigger ones have a chance to defend themselves and kill the attacker, while the smaller ones are easy to be killed and eaten, but reproduce much quicker. I don't know, just a few ideas, I'd really like to see the animals get expanded. Otherwise, it's great fun!
Oh, and what the heck is up with birds? They just fly out into the ocean in these big clumps and stay in the same place for me.
