Hi!
I made a duel game for Windows called Battle Breakout. It's available on Itch.io for free:
ecation.itch.io/battle-breakout
It's a combination of Pong and Breakout and you can play against your friend or against an AI opponent. There are tons of different bonus items to keep things interesting!
It's most enjoyable with two game pads, but you can also play it with a shared keyboard or even with a touch screen.
Have fun!
