The goal here is more surprise/intrigue, but it certainly makes for a challenging game. To my knowledge, in world 9 there’s only one big instance of this near the end and I try to not give any other options so people inevitably would discover the idea. But trying things until it works could be a little frustrating for some. I would like to address this with a hint system, but it seems quite difficult to do with the engine! Maybe I’ll figure that out at some point :)
