Fun. The guns feel satisfying, the animation is great, controls are good, and I like the level design. However the game's enemies are a fatal flaw to me. They pop up right onto the screen if you're moving too quick and the fact that they can shoot right on sight never seizes to feel unfair and unfun, especially with the fast projectiles and one shot kill for the player. However you can respawn very fast which is nice lo.
Its good but would be significantly better if enemies couldn't shoot until like half a second to a second after they see you and if there was maybe an enemy indicator.
