Great music choice and fun animations!
I got pushed off screen while in the slime room of the sewers by a couple of the small slimes and a fly and the screen didn't change to the room I got pushed into. There were slimes on the far right ledge when it happened and the fly helped to push me out, then followed while damaging me off-screen. Entering the 2nd screen over to the right, with the platforms, fixed it. I was able to replicate it again as long as there was a small slime on the ledge blocking and bumping me off-screen.
