Cool game, I love playing shooters :) It's super nice that you had a tutorial at the start too as loads of games didn't seem to have one and expect you to just read what the controls are but then there's too much to remember at once :D
One thing I really didn't like was how sensitive the camera was, it would definitely be nice if you could change the sensitivity in the options menu! The second level was confusing at first too, I thought the game bugged out because my character was just randomly moving on its own haha.
All in all, nice game and I like how you can swerve the bullets :) Just needs some polishing here and there!
