A very in-depth game with a cool mystery and "Escape Room" vibes! I really liked it! but I had one major problem, The interaction with the items and surroundings was confusing and unintuitive, I was stuck very quickly in the sink puzzle, and not because I didn't find the box and the sink, it only because I needed to click it with my mouse, I had no idea that I should interact that way, since before ahead I picked and placed chairs with E and Q, and moved with WASD, I totally assumed that the game was played only using a keyboard, I only figured it out after looking at clues you have given. I think that all interactions with items should have been reduced to one button (E for example).
but anyways I still had fun, and enjoyed this game a lot! Good job!
