Leading Up (U-Bahn with Empty Clues)
(Published yesterday, 00:00 by cyddrdrd)
Rules
Draw a totally connected network through the centers of some cells in the grid. The network may branch or turn, but may not have any dead ends. Clues outside the grid indicate how many times the corresponding line shape (empty, cross, branch, straight line, or turn) appears in that row/column, regardless of rotation.
Thank you maddie, Piatato and Christounet for testing and suggestions!

It took me a while to understand what was going on in this puzzle. Once I did, it turned into the most fascinating u-bahn solving experience I had in a while. Very hard indeed, but very satisfying too if you commit yourself to some deep thinking. Thanks :)
