Behind the scene

Spoiler

what I have to do now?

I love the premise of this level. Having a stage where B can enter from the left and exit on the right is awesome! I also like how the ending allows the player to see what was happening "behind the scene['s']" - phenomenal!!!

I have a few suggestions that could be quickly incorporated to remove some of the shortcuts and difficulties with the game:

Spoiler: Shortcuts

It turns out that both internal staircases can be avoided with a shortcut each:
- There is a draggable block on the bottom right mechanism that acts as a stop for the one above it. Thus, B is not required to act as a spacer to actuate it; and
- One can get B to the lift (the single block and slider) either from the left below-stage platform or (with a bit more difficulty) from the left moving cover and/or the latch.

Spoiler: Suggestions

The first red brick helped me make the first move. The second red brick is just confusing though. Instead, another red brick (or a grass block) opposite the first red brick to indicate the second dismount spot would help. Or you could have four red bricks for the start and end of each route through the back stage. Or, if only using one pair, make it for the second staircase as it is the harder of the two to find.

If you will update the level, please consider also removing the single metal block behind the stone pillar on the mezzanine platform. This level is amazing enough that it doesn't need any red herrings.

A bigger ask would be to somehow block the first staircase like when the stage pit cover moves out of the way in order to force B to use the central pointy vertical slider to get back up on stage. As it is, this can be circumvented as well.

Thanks for an incredible and nearly perfect level!

@meko You're going to want to get on the lift. it's not obvious from where you are at the moment. So here is a hint:

Spoiler: Hint

In order to get on the lift, which starts in the stage pit, you'll need to get back stage first.

@meko Although technically correct, my hint above may not get you far. So here is another one:

Spoiler: Hint

More specifically, the route to the stage pit starts sort of opposite the first red brick (and ends I guess sort of opposite the second red brick).

@B Hill

Spoiler: Have you tried

Have you tried to push and pull on the dark draggable on the right end of the motor and rail? The motor acts as a fulcrum/pivot.

@B Hill - awesome! I was afraid that you would get stuck (for real and not just an oversight) at the same place as @meko . Looks like you solved it the same way I did: using a shortcut for the second set of stairs at first and then going back to replay the level the intended way. The shortcut is much easier to find than those stairs, eh?
