Oh, making this on your own is a whole different thing :) I misinterpreted the credits, I thought that was the team. And about the models: if you want to have smoother models, texturing them will help you a lot. Instead of making the amount of vertexes bigger, you just make it look like they are (I'm not a 3D artist either, but I've tried getting my hands on it). Again, this game has a lot of potential when finished!
