Loved this game, I love games in this style, Simulacra, Sara Is Missing, Emily Is Away (which I can tell this is most likely the biggest inspiration), all great games in such a specific genre and this game goes along with them really well. I know you don't want spoilers so I will keep it brief, but I really enjoyed the puzzles, they were really creative, and made you feel good when you solved them.
I'm very much looking forward to a sequel and anything else you come up with.
