Towercraft

Very polished game! I like the hex tile style and models, and I like how, like a roguelike, you pick from a set of randomly generated tiles. I like the change in music and tower customization.
Foes are a bit strong, or towers fire a bit slowly...

This looks promising, but I'm not sure about the tile lottery system. I started a game that had no tower tiles available in the first set and could only watch helplessly as the monsters strolled up and attacked my base. But...am I overlooking something?
