This is a medium - hard testchamber for a co-op team.
The design is easy handled, but the correct solution isn't.
You need to think outside the box to solve it!

Map with an otherwise challenging puzzle, of the brainy kind, mired in zero indicators and shaky mapping. We wanted to finish it because of the difficulty, but I doubt anyone else would be so caring.

Can we have some dotted lines, please? It really was a shot in the dark, to figure out how the funnel would get changed in the end: and it completely screws up the previous part's navigation as well.

As mentioned, all in the level's looks appear depressing and unencouraging to continue and see what happens (hint: it gets worse). Bug: we absolutely couldn't manage the infinite fling, I think you need a slightly higher ceiling. Also the vertical fling part can be skipped with paint and sniping to the top.

I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

Very hard map, Most challenging I have played. Noice

Very good map. The most tricky part was to discover that doors above open just from one cube and second is not necessary. After that rest was relatively straightforward. On my list top five but difficulty way below complexo map made by Jonatan. 5/5 from me. Thanks !
