How to Use
• Click "Start game" to begin • Your goal is to protect the central core from destruction • Red projectiles are dangerous - block them by pressing and holding SPACEBAR to activate your shield • Green projectiles are safe - let them pass through to the core • Your shield appears as a temporary barrier when SPACEBAR is held down • Position your shield by moving your mouse cursor around the core • The game ends when too many red projectiles hit the core • Release SPACEBAR to deactivate the shield and save energy • Watch for increasing difficulty as more projectiles appear over time
