3. Level 3 modification: changed animation and design of the enemies, added planets as environment obstacles, added black holes as another damage effect to the player and enemies, changed sound effects (enemy's fire, player's fire, enemy's death, player's death), enemies respawn after getting shot/dying
   
4. Level Boss modification: added a boss enemy that's more difficult to hit, added a maze as environment obstacle, added an enemy with more invincibility, changed sound effects (boss's fire, player's fire, boss's death, player's death)
