This is a good game! Most of the issues like the physics and fullscreen stuff has already been said, so I wanted to say something a bit funny.
I think I ran into the exact same issue that and Null did. Two pieces of soap I needed ended up getting stuck behind a large pipe, and I couldn't grab them, but instead of throwing in the towel, I tried to almost "fish" them out with a loose piece of pipe that was laying around, and then I proceeded to accidentally push one of the pieces of soap out of bounds, where it respawned within my grasp!~ I then spent a while trying to get the other one out of bounds too!
If you ever decide to work on this game more, having things you need behind cute physics puzzles like that could be neat!~ (just with a little less OOB jank I think :P)
