Color Buster!

Color Buster! is a simple mobile-app tier Pong-meets-colour-matcher game where you move a paddle under bouncing balls. When you hit a ball, your paddle changes colour. If you hit a matching colour ball, you eliminate it. As you can see the goal is to hit the matching colour balls to remove them all, by carefully choosing the order in which to hit the balls. This is the same tier as a Unity Asset flip (although I couldn't discern any asset pack this might have been copied from). Based on the game menu, this was intended to be a mobile app, but there's no evidence of this on the app stores... presumably because the app stores have QA and barriers to entry that Valve doesn't. This is a very shallow game with little to no interest for serious gamers. It's worse quality than free mobile apps, but the developer is seriously trying to charge money for this on Steam. Impossible to recommend.
