Hi, I noticed two minor issues while completing the normal game:

1, on Slightly Nonsense level4, first room: if you go to the top-left corner of the room (just reverse the gravity), you can't switch back the gravity any more and get stuck.

2, on Slightly Nonsense last level, if you die once, the sounds are turned off and don't come back until you exit the program.

I played the game on a Galaxy Ace2.
