Sacrificing sacrifices?

Until recently, the game allowed "sacrificing" platforms without losing (as long as the player was not on the disconnected platform).

The problem with this is that the generator sometimes produced puzzles that required sacrifices; I thought about detecting this situation and filtering them out, but finally decided to directly forbid all sacrifices.

This makes the rules more consistent, but now I'm wondering if maybe I went too far. Sometimes the freedom to sacrifice platforms feels good while playing, even if it does not serve the purpose of solving the puzzle.

Maybe detecting mandatory sacrifices is a good middle ground after all. I will have to do more tests...
