This is a solid entry. I liked the cutscene at the start. The movement and shooting felt pretty good :)
An indicator that shows you that you got hit would be nice. I thought the first two rooms were by far harder than the third one, because that was bigger and it was easier to outmanoeuvre the enemies.
I also think I encountered a bug. Sometimes, after I died, the lift brought me to a different floor.
These are just some nitpicks, it's overall a very fun and nice experience :)
