Maybe 3 stars is a little harsh, but I think there is a lot to be desired in this design. The bulk of the level doesn't serve too much of a purpose, it's mostly just a couple of simple shortcuts with added combinatorial options for confusion. While I think it is an okay test of macro path analysis, I think most people just feel around until they get lucky and don't quite understand why the solution is any shorter. At least it looks like a spaceship.
The solution isn't super interesting, and there are a lot of false paths that aren't notable that could throw off a beginner. On top of that, level is kind of messy and difficult to look at.
While playing, one feels as if there was no mercy, indeed. But after solving it is clear, that there is at least a bit of mercy. ;)
Another great level!
