The graphics are great!
Controls feel a bit slippery, but can adjust.
Aiming is kind of a pain, you can only aim in 2 directions, no diagonals or up and down.
The movement sound is kinda weird, other than that, sfx and soundtrack are good.
The ai is.. well I'd say it's good, it doesn't get stuck often enough to make the game unfun.
Overall, great game for an evening, hopefully it would see some more depth added and improvements, cause damn, the graphics look great!
