Fun game
Reminds me of a lot of old school overhead shooters. Raptor was my favorite, and for some reason, this reminds me of it.
The only problem I had was the upgrades - They weren't very well explained, and when I made a bad decision, I couldn't wipe my game data (without going into my appdata, of course), to restart. It just shoved the same upgrades down my throat. All in all, though, a very fun game.
