Bloom Shield is a casual tap-to-defend game about protecting a flower at the center of the screen. Pests spawn from all edges and move toward the flower. Tap pests quickly to eliminate them before they reach the bloom. The flower has limited health—each pest that gets too close damages it, and the run ends when health reaches zero. The game features an endless wave mode with no fixed win condition. As waves increase, pests spawn more often and move faster, raising the challenge. Score points for every pest you destroy and earn bonus points when completing waves. Your best score is saved automatically so you can keep beating your record. The main menu offers Start Game, Help, and Exit. During play, pause anytime to restart, resume, or exit. When the game ends, view your current score and high score, then return to the main menu.
