UNCHARTED-1.

The level starts out with a bunch of really fun tricks, with a little non-linearity. For that, I would give 5 stars.

But then there is an often failing mechanism, followed by R walking around on top where the player has to wait a long time. There is 1 trick for the player to do, but I don't like that trick.

But good job on the first part, it was really fun.

I've given 5* for the grandeur of the design, the mechanisms, plus the trickiness. Although the obvious mechanism usually misbehaves it does not usually affect the gameplay. My first sight of R was followed by non ascent- was this another malfunction or is there a hidden ball somewhere. I had some trouble getting R to go the correct direction but my biggest hurdle was the start. I have always struggled with the plus version of this move. All in a great challenge.

Levels that are constructed with the two users are usually better. Two thoughts are better than one

Spoiler: Video Solution.

A tricky and entertaining level. Also the machanisms are great. Thanks

You deserves five star for the nice design

Full of tricks... And finally arbot reached the end.... Mechanism was perfect at time

4.5 stars, but the ToA after ball #4 isn't doable now. B BB'd to drop, but he tended to get stuck, causing a restart.
Alot of the moves were beyond me, so needed the VS for guidance.
Also, the plank that's displaced by ball #5 would fall out prematurely & cause another restart.
All in all, I njoyed playing & think this might be a keeper.
