Bloccy 1.2 Incoming

I've been meaning to post a Bloccy 1.2 update for a short while. Only got 1 or 2 bug fixes, nothing major. After that I'm debating where to take the game if anywhere. More levels with the same mechanics? New mechanics? Update the style? New game modes? I'm opening myself up to suggestions, or do I just quit while I'm ahead and leave it with a perfect 39 levels?
