I cleared 5 floors.
The game looks, sounds and feels good, the speed of both the visuals effects and the gameplay elements (protagonist movement, bullets) feels right. I like that you put some power-ups there, and even keycards (the door opening effect is nice) are a nice addition.
The variety of turrets which are there is fine, I like the mix between fixed shots, changing shots and targetted shots. Some moving enemies would enhance the game.
Cool game, thanks for sharing.
