Ok so I've done pretty much every puzzle in the game, the only 2 paths left to go down are the exit and one unexplored bit at 'laying the foundation' where the balls smash through the walls in the centre.
Is there any strategy to this? I've heard the solution is just to brute force it but it simply doesn't work for me, what is going on here!?
Try moving, then stopping for a second, and repeating. It is luck-based, but move-stop-move keeps the balls changing between red (outside of the white wall) and green (mostly inside), which means they'll take more trips through the wall in a shorter amount of time.
Seems to be the only way. Placed blocks get overwritten by the white wall, and you can't directly interact with the balls. If you see a hole nearly large enough, make a dive for it.
