Glad something else caught my eye before buying it.
I ended up getting Tilt Me.

Sort of like Labyrinth gameplay, but a maze with no holes, except one, and the goal is to arrange 3 balls over targets to finish.
It has a full 3D maze, which tilts a different angles like that Zen Pinball. The music is actually a sound effect where as the glowing ball travels, it trips tiles that play the music. The faster the ball, the faster the music. And the tiles have a cool glow as you pass them.
Overall, a very retro feeling game. A new update game out with an update that changes the colors each level, and lets you choose how many balls you want out at once.
Also works well for quick play. No menu or settings, takes you were you left off near instantly. Settings are in the main iPhone settings area. I wonder if the levels are random.
