◼ The enemy fires bullets at regular intervals.
⚫ System
◼ The bullets move forward at a constant speed.
◼ When colliding with an opponent’s bullet, health decreases and the bullet is removed.
◼ The exact timing of the collision is up to you. (It could be a time when the character’s center meets the bullet, or the character and the bullet overlap at least one pixel.)

◆ Win: When the player destroys five enemy.

◼ Enemies are destroyed even if they are hit once by a player’s bullet.
◆ All-fail
⚫ You can toggle the “all-fail” mode by pressing “f” (Default: off).
⚫ When the “all-fail” mode is on,
◼ If the player gets hit once, the game is lost immediately.

⚫ If you implement additional functions unspecified in this document, you can get extra points, up to 10% of the full score.
◼ This should be stated in the report.
