Nice game :) . Since in games like these I always focus all my resources on workers at the beginning, it was pretty easy to beat, but great effort. I liked the theme explanations in the game description ^^ especially the FPS part. In browser games that really is important.
The game has everything a feature-complete game needs: Gameplay, menus, sound, music, how to, etc. Great job!
One thing you could improve upon would possibly be the miner-ai. I had quite a few of them and they all seemed to bundle up/bump into each other on one resource. Having them spread out a bit might help.
