This is the first game I've ever played with an Rebirth system, so whenever I see a game with an Rebirth system now I say "It has that cookie clicker mechanic"
you will love the first golden cookie combo with "force the hand of fate" :D (spell from wizard tower minigame) the number of cookies it gives is just so jawdropping when you first do it hahah
mild spoiler ahead. once you get your first sugar lump you should use it on your wizard tower. the second one you get you should use it on your farm. there is more to using sugar lumps other than the extra CPS that it tells it gives you.
They dont actually, you can get most of them in a month or two, the game is really easy once you've played it long enough (Knowing what to do from the start.) But even then, getting all achievements isnt possible unless you know what your doing from the begging of your run.
