The concept was super interesting!
The menu/UI was confusing, at first I didn't really understand how to change the room parameters or access the photobook/hints, I am glad that's on the working implementation.
The biggest hints I missed was in regards to knowing which parameters still had creatures to be found, as in "you're missing 3 night ones" to know to come back to that specifically.
Aside form that super cool ideas, the phantoms were also extremely cute, I want one of these in my room now (maybe I have one and is invisible???)
