I couldn't beat the game. I was a bit lost as to what to do. Then—I don't want to give spoilers—I went somewhere and there was nothing there; I went back later and things moved forward, though probably way too late—or maybe not, I don't know. I think I get the concept behind it, but I feel like it isn't really explained to you.
And right at the start, it says "press right-click," but it's actually left-click lol.
It's a great idea, though.
