Zoom! is an arcade-style puzzle game where you play as Zoomer, a Pacman-like character with arms and legs. Your goal is to trace the outline of the squares on the game board to light them up, forming full squares to earn points. The game also displays how many lines must still be completed, adding a sense of urgency to your progress. As you proceed, various monsters will try to hunt you down, costing you energy and eventually a life. However, there are also power-ups available that can aid your quest, such as quick filling of tiles surrounding the bonus piece, level skips, and bonus points.
Gameplay is fast-paced and action-packed, requiring you to think strategically about which squares to light up first. You'll need to balance the need to complete lines with the risk of encountering monsters. Power-ups can be used to gain an advantage, but using them too frequently will leave you vulnerable to attack. With multiple levels to complete and increasing difficulty, Zoom! challenges you to stay focused and think ahead.
