I watched for a while, and there is some crazy stuff happening. You could give the player evolution points every now and then he could spend on adjusting his tribe in one direction. Or be a god and have a natural catastrophe every now and then.

That kind of already happens - when a critter reproduces, its stats get passed on to the child with some slight random mutation. Same goes for bullets that kill critters - any bullet that kills a critter shifts the entire tribe's weaponry towards its own stats by a small amount.

It's a bit more obvious with the bullets; for the critters I think the game might not usually last long enough (and too small in scope) for a significant variety to show.

I guess I could slowly increase the number of points available to the player to spend on their tribe with number of games played or such... will have to look into that.

Strange game. I don't really get it. I love title screen
