📝 What does this PR do?

• This PR aims to add a mechanic that punishes the player for attacking too often. The player can previously use their attack, which attacks as fast as they can press the spacebar, and move side to side to trivialize the game. This PR adds two new features: a cooldown to the player's attack (333ms) and a new enemy. The new enemy is an asteroid, and the player is disincentivized to attack it. If shot, it will explode into five projectiles that fan out toward the player, which cannot be destroyed. These changes should make the game more engaging to play.
