You have the start of something here. As others have said, it doesn't seem finished yet. Sound effects are good. I like that "Age of Empires" caveman-speak. l like the idea... it's somewhat addicting and I did get better as I played, so I'm going to try to highlight the problems where I think they are.

Most civilization-growing RTS games are filled with upgrades to increase gathering, production, and technological growth. Maybe you were going for something faster and simpler, but even then it seems to be lacking something.

Beyond that, I ran into some issues. First of all, the price of food resources goes up too fast. Before long, I can't even afford to buy anymore without having the guys collect more raw resources. The problem is, they guys are all dead or fighting by the time they're done doing that, and I can't even get the food out fast enough. That's another problem: they get hungry so fast that it's almost impossible to do anything other than eat. And even when I give them the right resources, they break down into in-fighting before they can start collecting.

The fact that resources can appear randomly on the map is a problem, too. The only way to attract the guys is to click the resource, but a lot of times, a) they don't make it across the screen without dying or fighting or b) the clicked resources are too far and they've already faded away before the cavemen reach them. They just fade too quickly for that sort of mechanic.

Another thing: the guys seem to be a little gitchy. They often get stuck and just stand there doing nothing for a while. Sometimes they walk halfway across the screen and the come back. Sometimes guys with full stomachs reach the food an eat it first (which may be intentional, but lack of control over this makes it difficult to succeed).

Maybe you were intending to make a very fast survival challenge, but it seems that your players are looking for something more involved. Yo do have a good base for something greater, so think it over.
