Oh my gosh??? I really enjoy this a lot :D
This seems like a really solid start! Mother is terrifying in the best way and I love the weird mix of sympathy and mistrust you've built between Fourth and the other caretakers.
I got to level 5 after killing the various blades in the lil blade room and opening a nearby cabinet and the screenshake (and column of light) just got worse and worse and wouldn't stop. I turned it off in settings and while that fixed the screenshake my camera no longer looked at the protagonist and the glowing light was still there. Going back to the lab did nothing to stop this.
EDIT: also one of the boss' vertical punches hit a pillar and it froze up. I couldn't attack its weak point and it wouldn't stop being stunned.
a couple of other things: I feel like most of the enemies attack a bit too slowly to be much of a threat. It might be worth upping a bit. Or maybe decreasing how quickly you regen health in combat too. The fact that every enemy drops stuff you can absorb and use to heal yourself means that unless you're fighting something that doesn't drop anything like the ghosts in the pump rooms, you'll probably be able to outheal pretty much everything.
I like the base framework you've got going here though! Looks cool.
Also do you think you could add transparency as a customization option?
HEY be aware that this is incomplete and really not more than a rough outline with a bit of writing near the beginning. Courses were more strenuous than expected. in any case work on this will continue and we should hopefully be able to get stuff more polished. For the time being note that playing this will likely have anything close to what would be a shocking plot twist in the final version spoiled for you.
