Awesome game idea! I really like the challenging aspect of the game. The bgm/sound effects fit well.
Wonder if there's a max amount of red balls or they keep increasing until you lose.
Maybe immunity for a second or two after getting hit.
Hi Port, Thanks for the feedback! I think implementing a menu for key binding would help with players who have preferences for which keys to press. Your feedback also gave me an idea for adding a charge bar that shows how fast the ball is going to go.
