Another 2d pong game created in Godot: https://jdzsk.itch.io/unfair-pong
TriJam entry. This was made in MORE than 3h though, so I'm out of competition - still, I hope you enjoy it!
I tried to make it online multiplayer, but didn't have enough time - maybe will add later. So I ended up reverting it back to couch co-op. So in the end spent more than 3h.
Other than that it's a simple 2 player pong game with a twist - player who lost a point gets an unfair advantage. Whoever gets 10 points wins.
Had a little challenge for myself - don't use sprites, so all the shapes are built in Godot shapes (Polygon2D and Line2D).
