Extremely nice game. It is a bit short, but the music is what really got me. It took me a while to realize it was cortana- I thought it was Kerrigan there for a second. Awesome, Keep it up!
The game, at this stage, is crazy buggy. Enemies come too fast for the fire rate and the turrets do nothing. Also, fix the accuracy in the aiming- I've had several shots go crooked or just go through an enemy. IF this game were to be fixed, we'd have a winner. I think teh only redeeming factor here was the music. Just playing for the badge it seems.
