I am really glad that I decided to go into this game blind, because damn that was wild.
One minor nitpick is that, in the particularly tall room (forgor which level number it was, but the level with multiple waves of enemies that are meant to be fought on the way up), it was possible to somewhat cheese through part of it (being able to shoot and kill some of the higher-up enemies effectively for free, before they got activated), so it might be worth considering some form of anti-cheese for that (maybe making the player feel bad about cheesing it, perhaps dealing some damage to their self-esteem because of their somewhat dishonest approach to the situation?), but basically that’s the only nitpick I have.
Congrats!
