I like the concept of "Spot the Difference" in this game. But since I have a bad memory, I had to poke each object in the hope that it was a different object :D
"sanity" indicator left me in suspense for a long time, and it's also cool that some kind of creature appears in the window.
Special thanks for warning about jumpscare!
But I tried to play a second time and started to play on purpose - the "sanity" indicator is empty and the screen is darker, but the monster didn't attack..
