Loved it!

I love this kind of games: life simulators. This game is very polished and I belive it will get a good place in the competition.

Graphics: The graphics are very polished. The menu and HUD look very good. The only minor issue is the caveman-breeding-cooldown bar. It doesn't fit the rest of the HUD very well. It should be more caveman-ish. The animations are also good, but they could be a bit smoother.

Sound: The sounds fit together nicely, but the background music is a bit too repetitive. You should add more background music tracks. I loved how the cavemen screamed for their lives when they were being mauled by dinosaurs. >8D

Gameplay: It's a life sim. It rocks! You can teach other cavemen to hunt, forage and prepare food. This is a really unique and interesting feature. Different predators come to atack and you need to defend against them, as well as against rival cavemen. There are also lots of bonuses that appear over time, but I think you should add some other upgrades: farming, hunting different dinosaurs for their leather and fangs, taming some dinosaurs etc.

Story: Well, there's no actual story, but generally, life sims don't need one...

Interface: The interface was great, and polished, and there was only one minor problem: pausing the game just froze it and waited for any key to be pressed. It needs to give some feedback to the user... a message like: 'Game paused, press any key to continue'. Another suggestion would be enabling hotkeys to quickly breed cavemen.

Overall: This is a relly great game, with polished graphics. I love it. :) It's really addicting. Great job. :D
