Ah, That's a shame. I was hoping it would be a multiple angles to solve a level kind of situation which would allow for that sort of filtering or at least the kind of alternates you had in OPP, but I can see how that would make singular solutions nearly impossible. It was realizing that the solution to the prototype was behind a kink I try to avoid that prompted the hope, but I can definitely see how that would complicate your vision for the final game.
