Nice shooter game with good visuals and nice atmosphere. The movement speed felt too high and mouse sensitive was to high from begin. But Gunplay felt good and upgrade/trading system was motivating.
Some more Sounddesign for the enemy would be good as it felt a little bit empty without the music. The music was good, but a nice DOOM like action soundtrack for hunting down monsters would be cool idea. :D
Felt like a polished and finished game. Good work!
