Thanks for the feedback. I find it interesting and helpful to hear which parts of the game people might find difficult to understand. If you have any ideas on how to make certain sections clearer, or how to give hints about what to do, I'd love to hear them.
I have some ideas about how the stamina mechanic could be used in the "real" game, and the concept for the "real" game turned out pretty good, too, so maaaybe someday I'll actually add a section featuring the "normal" game.
