Congrats on making a game that takes satisfies both themes and fulfills all of the challenges to boot. Gameplay was simple and addictive, giving great arcade vibes. One thing slightly unintuitive was the control scheme, where the A and D buttons were a little harder to get used to since players normally associate them with left and right, and once you cross sides the buttons are "inverted". One alternative would be to use the up and down keys (or WA) which feel a little more direction neutral for increasing or decreasing the distance between balls. Other than that it was a well made game with well matched graphics and sound. Kudos.
