This game is great, has so much potential with a bit of polishing this game could be one of my favourite multiplayer games.
A few issues I've noticed:
For seated players thr game goes to the wrong position after the groe/shrink power up forcing me to turn seated on and off to get back to thr proper height.
Sometimes while trying to grab the ping pong ball it slips out of my hand and disappears or it shoots out of my hand and disappears. I think a fix would be to respawn the ball if it's not lifted past a certain point. Hand Tracking could improve this game greatly also the ability to transfer your home avatar in game also.
Now to finish up, the YouTube system needs a big upgrade. It's hard to find videos you actually want so a better idea is to get rid of the YouTube machine and control the YouTube videos via your settings and showing a "YouTube" like page on the big screen where you can search all the videos instead of a small little screen with a selection of a few YouTube results based upon your search. Maybe you could give us the ability to host videos in private rooms sort of like bigscreen, that way people can make a YouTube playlist on their own devices and host it in game.
