Nice shooter. The level design is interesting. I also like the music and the sound effects. I think it would be better if the enemy had more response to the damage. And there is a problem when you get the bomb and backtrack out of the green room. The hallway is narrow, and the player can easily be pushed out of the hallway before the door locks. The player can't kill the enemy to unlock the door because they are on the other side. So, the only option is to kill yourself and respawn, which can happen multiple times. Other than that, the game is quite fun.
