Understandable. I should have put the controls on the main screen. The default keys are the left and right arrow keys (to move), space bar (to jump), R (to reset), and Escape or P (to pause). These keys are also re-bindable in the pause menu. The goal of the game is to defeat the enemy in the center by reflecting its bullets back at it. You do this by moving in either direction around the enemy and jumping to a further point to create a line. The line has a color corresponding to the color of your character (which changes randomly each time you jump). The color of the line has to match the color of the bullet for the reflection to be successful. Additionally, the color of the bullet has to match the color of the enemy health bar at the top of the screen in order to do damage. I hope that helps. Thanks for playing my game!
