Spoiler: Info No tricks are required. Remember there is a little hidden thing..... Spoiler: What's this? Drag it! And pay attention that what changed..
Can't say I really enjoyed this one as the hidden caused me several restarts when I was near the win. Thought that I had explored it fully, but turns out there are more hidden. In fact, I like the ball paths and logic there especially the ball in the tower. And I sent B to the win. Nice design as well. Thanks for sharing @Lang Tao Jin
That was a clever one and took quite a while to figure out what all the sliders did. At one point I had B and then R underground trying to figure things out! LOL
