Let me put it like this. As it stands, you are charging 15 bucks for what is essentially a bunch of models with walk cycles walking around in a field. I'm sure there is a decent game coming here but this really feels like it needed more time in the oven before this came out. And judging by a few of the other comments ive seen too, I'm not the only one that thought there was going to be at least SOMETHING here. I understand what an alpha is. I'm not expecting a full working game, hell ,I wouldn't expect that for a good while now.
I would rather think this is a case of bad communication of what was coming out in this initial release rather than what to expect.
