Thank you so much for such useful tips! Now the game is not blurred, there are controls on the game page and in the game itself!
But unfortunately, the full-screen mode itch.io it doesn't really help to run the game without cropping parts of the camera, so I didn't change this setting
And something else - the doors themselves do not open, they are opened by gears, which sometimes you have to look around the house. However, this gives me the right to put the "puzzle" tag)
I suspect that you are stuck at the moment with the passage to the long corridor on the second floor, because Pogchamper is very hung up there, xdxd
If you suddenly re-pass, the answer will be on the second floor)
Anyway, thank you so much for the tips!
