So far it's the best use of the theme that I've seen. I love tower defense and crafting games, so combination of both works very well for me.
At first I didn't know what to do, some information about controls would be nice. But after few tries I've managed to (barely) survive for long enough that infinite wave was a piece of cake. Here's a screenshot of my end game:
Awesome game! I like how placing entities is very forgiving and it's snapping to grid very easly. Cheers!
Perhaps it's just that I don't like tower defense games, but I didn't find this to be very different from a standard tower defense game. You're still using resources to build towers, so I don't find these genres very incompatible or even very different. That said, It's an effective tower defense game. I do wish there were more explanations of things. I thought the saws were bows at first (and the stone mining looks like a catapult)!
You nailed the theme but there is a lot of room for improvement. Some in-game instructions would be helpful as it is a pretty complex game. Also, the start is pretty slow. As far as graphics go you did a really good job considering how much time there was. The audio was lacking however which is unfortunate because audio is such a huge part of video games. I'm really surprised you were able to achieve so much in such a short time good job!
