If you want music box, I think it's better to set the values inside the code directly. But here's the improvement you're looking for. I added extra functionality just because it's so easy! :)
Tap Counter. Not a game. It's a screen full of buttons that you tap to increment the count. Something like a little clicker that you push to count, except you have a lot here.
I like the sprite 298 best. No need to scale it. I managed to win with difficulty level 6. Despite not having auto tile removal, the game is actually fun with the stylus.
