ANOTHER BLOODY TRAP!

I had this idea to implement into an area of one of my dungeons. It is a maze of sorts where where the player is only permitted to take X steps across tile A and Y steps around tile B before becoming stuck and having to start over. It is in a cave as well, so vision will be slightly impaired.

I have a strange feeling that a RM game has done this before. Either way, I'm gonna do it, don't see why I shouldn't, but is there another game that did this, RM or otherwise?

Surely the best way to code such a thing is with a parallel process that tracks and totals specific terrain tile variables, right? Haven't started coding yet, just having a thought while I doodle potential dungeons.
