Fun 3d shooter game. The shop and upgrades was an excellent touch. The sound and music were great as was the graphics, really liked the animation of the skull talking at the beginning, if you had more time and lined up the movements with the sound it would have been super impressive.
Only gripe is the difficulty seemed to ramp up a little too fast and the gun shot too slow, but better that than endless too easy.
Thanks for submitting, it was fun!
