I played this early on in the jam, a day or two before the submission deadline. At the time, this game was marked as a work in progress. That might have been 0.1 but maybe not, I tried it again today and it seemed to play the same.
This one's weird in that it's a good pong clone, but not a fun pong clone. Hitboxes and physics feel right on, but the enemy AI is too good and tends to hit the ball in such a way that slows it to a crawl. There's a neat background, but not a lot of effects or twists to spice things up.
The whole "adding an overcomplicated backstory to justify a dirt simple game" thing is hilarious, this used to be really common back in the day. Although… this seems to actually come from the existing Pong Kombat game, and isn't original to this jam entry, which was disappointing to see.
It is technically impressive in that it's a Master System game running in an emulator, though.
