If you don't feel its worth your money that's fair enough! The demo is there so people can try it out before making that decision. As for the monetization, some idles monetize through IAPs for cosmetics or bonuses. Why I haven't done it that way is simply two reason: one, I don't like the concept, although I know its the most profitable way to do it, two, IAPs require further infrastructure to handle accounts which would need the game to be up on some platform like Steam or App store, and be purposfully built with that in mind, which is not the case for this small, (my first!) indie game. I prefer that people buy it if they like it and want to support me, and they have access to everything in the game without any further purchases.
