How to Play BOING!
Quick start
Choose one player first and light neighbouring steps without moving diagonally. Watch the pin's column before crossing it. When the eater approaches, steer it beneath the pin; in later levels, follow the required row order instead of visiting any dark step.
Controls
Player 1: D-pad moves the bubble up, down, left or right; no diagonal movement. Native Game Boy player 2 controls the eater with A left, B up, START down and SELECT right. In the browser, player 1 uses arrows and player 2 uses WASD.
BOING! — About this game
A bubble bounces across a board of 36 steps, lighting them while a Bubble Eater gives chase and a pin descends from above. BOING! changes the order of the job across three levels: first any unlit step, then rows from bottom to top, then even rows before odd ones. You start with five bubbles, so a route that lights a tile but traps you against the pursuer is costly. Lure the Bubble Eater under the pin for a brief reprieve, or let a second player control the pursuer and turn the same board into a contest of anticipation.
Choose one player first and light neighbouring steps without moving diagonally. Watch the pin's column before crossing it. When the eater approaches, steer it beneath the pin; in later levels, follow the required row order instead of visiting any dark step.
