this was really well done and polished, made me want to keep playing. i think the shooting is almost there, it felt like enemies had to take just a liiiiiiiiiiiiittle too many hits and made the game not flow as well as it should. maybe seeing them stumble or react to hits (before death) would be nice. but i liked being able to use cover and i thought the bullet speeds were really nicely timed, so that i could strategize and properly dodge.
overall, really enjoyed it, nice job!
