I've been giving this a lot of thoughts so your feedback is definitely valid. I'm hoping to nudge the players through writing a smart description for the difficulty levels and through a few UI tricks. I'm definitely not hoping for a 100% success rate, but would be nice if it was more than 0 XD maybe like 30-50.
I've done a few prototypes of games that had no win condition and people are really insistant on finding the one way to beat the game, usually, so I'm not too worried about that. Worst case scenario I can always add hints if I see too many failed attempts. Actually I probably should.
