This level doesn't need tricks,so please don't use them (And I also don't see shortcuts) Spoiler: 1/2 Hint The rail is an "Half block"
Nice puzzle! First finished it with tricks. The I read your comment and thought "oh 'puzzle'!", no tricks?  Made me search for more possibilities to move B, and achieved it without tricks.
To move B with tricks isn't really a shortcut, The important thing is that the position of pieces to complete the "Tangram Puzzle" is always the same.
Another mind bender. Spoiler The layout makes the solution a bit more transparent than usual for your levels, but you still have to get all the pieces in place.
Now this is more like you meko . Second thought, if you omit the grass and stones, replace B with R, this could be a great entry for pds all-metal challenge.
This puzzle blew my mind, because first I reached the goal and then read your spoilers Spoiler I realized the isometric perspective didn't make me see the missing place for the solution
