Fun game! Its a bit easy to cheese by jumping over the fence where none of the enemies could reach you. Also, the screenshake when enemies spawn is a bit too much. I like the weapon and upgrade system.
aaaah cheater bouuuuh (it was intentional to be able to jump on the fences, it feels like it's cheating and 100% they will feel super smart eheh) I agree with you for the camera shake, i should change it !
