Whoa. A Tilt screen that shows how much bonus you just lost. BRILLIANT! Every modern pin should do this.
It would be awesome to throw in a special call-out mocking the player if the tilted-away bonus was above a certain threshold (similar to how some pins have call-outs for when your collected bonus is above thresholds).
And sophisticated code that can accurately detect when a player is using an unintended exploit? Wow.
Good stuff, Keefer!
