Dry Tunnels.

Another awesome level from you!

Spoiler

that rafting is so cool!

Hi @PvB, I was not able to finish yet because it is really unstable in my mobile phone: R most of times falls out of the level although I try to stop him with the draggable, B elevator most of times gets stuck and it doesn't move, first block gets stuck one tile before arrive to the end...
We already observed some times it depends on iPad, iPhone or Android some little physics differences... don't know if anything can be done.
Anyway, I will retry little bit more and thanks for sharing!

By the way, did you get the idea of balls from @richardfu_ Assembly Line level?

Finally I was able to finish (I was lucky and once I didn't suffer the issues commented above) and honestly, the level is great. As I already played @richardfu_ level, the balls didn't surprised me because I was aware of their behavior but I really enjoyed last step. When you think you are done... Thanks!

I gave up after many many attempts as the level looked great and the game was very playable but things were getting stuck and I guess a little unstable as per @chemi's comments. Thanks for sharing though.

It's giving my Galaxy tablet fits as well.

This level has the potential to deserve 5 stars, but it is highly based on mechanisms, and honestly I'm experiencing troubles with most. It is very difficult to get mechanisms to work very consistently, so some can be forgiven. But it resulted in frustration and I finished it twice, but not in what I think is the intended way.

R might drop despite the block being raised.
B might not rise.
Ball might not roll out onto the 'conveyor'.
No controllable way to get the ball to the end of the conveyor. You need luck that it goes beyond the second raft.
First raft easily falls of the platform.
Draggable in platform can hardly be reached when the raft lies on it.
Difficult to get second raft through the hole at the end of the conveyor.

I'm not sure whether the ball and second raft actually need to go through the hole at the end of the conveyor. In one solution I used the falling trick twice to go to the win, in another I used the draggable above the conveyor to drop all the way down (the conveyor itself was pushed to the location of the first raft). I was never properly able to walk through what I believe is a tunnel.

The fact that I did try all of this means that in potential the level is great. I really wanted to figure out the path. So in that sense it is definitely a great level.

It's a bit unstable but I still think it's awesome !!! THANKS
