i don't know if someone already said this (or i'm just unlucky), if you run fast to clean something and press to clean close to the end of it you will slide past it and you can't continue
Yeah, it's an old known bug; I'm very sorry, this was made during a game jam and I don't really have the time nowadays to update the game. Hope you still had fun, and thank you for taking the time to report the issue!
