2. *Enemy Movement: Enemies spawn with random directions, move at constant speed, and adjust direction upon collision, with a boost feature to prevent getting stuck.*
3. *Player Lives: Start with 5 lives; lose one per enemy collision, triggering respawn.*
4. *Lives Restoration: Restores 1 life every 5 minutes, even when the game is offline, with a visible timer.*
5. *Player Respawn: Respawns at death location with a 3-second invincibility period.*
6. *Enemy Revival: Enemies sleep for 10 seconds after being hit by a brick, then revive.*
7. *Side Portals: Teleport players and enemies between the left and right sides of the screen.*
8. *Bricks: Primary weapon; hit from below to defeat enemies. Variants include slowing bricks (slows player) and fragile bricks (disappear when touched by player).*
9. *Enemy Spawn Points: Two spawn points (top left, top right) with level-specific timing.*
10. *Game Points: Earned by collecting enemies (15), UFOs (15), power-up boxes (40), or hitting the boss (20/hit). Saved only on level completion.*
11. *Surprise Power-Up: Randomly appearing boxes grant points, speed/jump boosts, or penalties.*
12. *Level Management: Complete a level by reaching a target score and collecting all enemies; limited simultaneous enemies; game over at 0 lives until restored.*
13. *Boss Enemy: Appears at level 15 with 7 lives, teleports to player’s level per hit, speeds up near player, and dies permanently (no collection needed).*
