Cool game!!  I actually like that the dirt is a little tricky to see - there's a subtle difference in the floor texture and it adds nicely to character of the game.  Great work!

the dirt is really hard to see but its a fun game 

Nice concept, but the dirt is hard to see, nice job!

Kudos on the game.

I also had trouble identifying the dirt, but then I had a fun gameplay experience. Perhaps you could make adjustments to the visibility of the dirt and the movement speed as well.

Good job!

Took me a while to see where the dirt was, might have been a good idea to make it either flash or use a light palette! I like the concept of a ghost just taking it’s time out to clean and not haunt people though, that’s a fun idea!
