Just played it.
Looks like a really fun game! I would probably make it a bit more fast-paced, but disregarding that it’s a great game!

Another update. Those ‘lightning’ balls should be removed now and some collisions are improved.
Also added the ability to change the balls speed:
While holding F3 the score bar turns into a controller bar and you can increase/decrease it by pressing up/down.
The board (also the other ones in multiplayer) is controlled by the AI as long as you are holding F3, but you get or lose no points so you have a little preview for the new speed.
This does not affect the board velocity!
That’s a clever design choice. +1.
