Short, but well made! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

The paddle seems really slow. It would have been nice to have a variable movement speed similar to what you can get with an Atari pong controller. Also, a score/lives system. Still, good job.

Classics never fail to entertain for a bit. It's nice, and I love the screen shake. I think platform and ball should go a bit faster, maybe.

Pretty basic game, but fun as always. With a bit of polishing and some level design you can get a nearly finished game.
