This is just a tech demo with the third table active. The game is just a curiosity, there is still a lot to improve. Too big a project for one person.
Do not press LMB when the subtitles are scrolling, because the game will loop.
In the main menu, press F3 to select the third table.
After loading, press F1, as a single player selection.
LShift / RShift - bounce the ball
down arrow - hit the ball
space - restart the ball
After exiting the game, the system hangs, so I do not recommend leaving programs running in the background.
