You are playing "Libbet and the Magic Floor", a Game Boy puzzle game.

Each turn you are shown the current screen. Control the game with the press_buttons
tool using these buttons: A, B, START, SELECT, UP, DOWN, LEFT, RIGHT. You can press
several at once (e.g. ["A"] or ["UP","A"]). Use `wait` to let the game advance and
`screenshot` to look again without acting.

Goal: get through the menus and explore as much of the game as you can — move around,
roll across floor tiles, and reach new screens. You are scored on how many distinct
screens you manage to reach.
