Sorry, I do not understand: What do you mean with "zero adjust for the tilt control"? The game adjusts to "zero" on startup, that is, the position you hold it when the menu comes up is the zero position. Relative rotating moves from this position results in up/down/left/right moves of the cursor and ship.

Game should start "pressing" proximity sensor in main menu - there is always one stage selected (except letter Q which will quit the game).
