This game looks exceptionally cool. I'm forever in love with the main displacement shader you made, and for the first ten minutes I was just taking screenshots of every new prop and thinking how I want to make something like this, too. It's genuinely magical how good it looks. I liked the models too, and the squiggly textures are just genius.
The echolocation mechanic is very imaginative but not very accessible; I don't live alone so it was very uncomfortable to use. I went to the menu and was happy to see a toggle for it, but then realized there's no alternative button or something else to use instead. Not sure how players are supposed to find the passcode if they don't have a mic. I do respect the creativity of the mechanic though!
Disappointingly, I spent the rest of my hour with the game very frustrated. I never got the mechanic of the enemies and just echolocated into them until they disappeared before moving forward, to eventually unexpectedly get killed from behind (which was very much a traditional jumpscare every time). The closest I got was getting everything but the keypad code and then coming to realize that the code is randomized, and its position is randomized as well (and then I proceeded to get killed from behind). Really tried my best to see the game to the end but just couldn't. It is so, so punishing and running around searching for randomized items just didn't feel rewarding at all.
Also, the water tank mini-game broke the immersion a bit, would have much preferred something physical and in-space, even if just a button.
I'm sorry for this being so critical. Just wanted to love this so bad because it might have the best-looking visual effect I've seen, like, ever. Looking forward to your future work.
EDIT: Took a break and tried again. Tried a new and advanced strategy of sprinting around the facility ignoring everyone who isn't a quest item. Beat the game this way, the ending effect was pretty cool. Was this the intended way of playing?.. Or was there a stealthy tactic that I didn't get? Am I supposed to just turn around from a place where I see eyes and come back later?
