Love the twist on the gold game. The bouncing pads and red sticky wall made for some interesting situations and I LOVED the yellow bumper that spawned more balls. There were some very chaotic situations where the balls were flying everywhere and I love how you tied the control of each ball together.
One suggestion or fix: sometimes the ball would get stuck in the hole before I hit the yellow pad and the game would just stop without any prompt and I was confused at first. Maybe add an automatic restart, or prompt to restart because I didn't know what to do, I thought it was just frozen. If you really wanted to, you could make it so that if you only have one ball, it cant get in the hole until the other ball is already spawned. Great game! I really enjoyed it.
