Gotta love some Pong. Managed to get my partner to play this with me and we had a lot of fun (once we'd read the controls and knew how to use those abilities!). In game UI telling you the controls would be good, and as someone else mentioned, a cooldown for these abilities would have felt really cool. I also would have loved to have just seen more (don't take that negatively, it's a game jam game after all!) because i thought it was good fun, would have been good to play a few more rounds / get more abilities etc.
All in all, great effort. Well done!
