Hi, my comment is similar to the others' ^^
Nice gameplay loop, sweet atmosphere (music loop, sfx, cat mawing in a cute way), the visual filter and screen transitions are smooth. The reference to Luigi is cute too :)
I just got confused as to how we're supposed to find the cat, or what the cameras do for example. Having to figure out some stuff while playing is nice, but here I didn't have a clear goal. That would have made your game a very good game instead of an ok game (I love the idea of using the Schrodinger Cat reference too so I'm sure if we understood your game we'd love it instead of like it !)
If you add directions on your page and want me to review my rating I'll be happy to do so !
