In what way does your game fit the theme?
The primary mechanic of the game is that the player must attempt to shoot and destroy invading enemies. However this can only be done if the projectile that they fire is in a "rewinding" state (initiated when pressing the space bar). This means that the player has to strategically plan all of their shots so that when they make the projectile rewind, it will destroy enemies.

Did you write most of the code yourself and made all the assets from scratch?
Yes
