Discounting various bugs (such as being able to continue even when dead) since I don't know if it's on my end or not, there are two things I feel that can be improved on.
Firstly, zoom a bit more to show the entire room. It's not that distracting, but for those room-baesd shooters, it's a nice little QoL thing.
Secondly, there was a few moments when I entered a room and immediately got blown up by those exploding turtle things without being able to do anything about it. Something I've done in the past is having enemies have a short cooldown period of you entering the room so you have time to take things in. It could work for this too.
