Counter-opinion here, I appreciate the variety immensely. I also very much dislike the general prestige-prestige-prestige again systems of most incremental style games, and much prefer this style of "hey, learn new stuff, figure out how to get really powerful, then we introduce another element"
I enjoyed the multiple elements, but they felt a bit uneven. Like the first world was just so dense and all the upgrades interconnected and led to all this great layered experience, and then boom you start doing alchemy, and you start doing carpentry and not only did they not really connect, but the first area just became completly forgotten. Which to me felt like a step back because the first area was IMO head and shoulder the most fun. If the first area with its mixing and matching of magic somehow played more a roll in the other areas throug hte game it would have been a better experience in my opinion.
It's kind of a pet peeve of mine in idle games when you have all these buttons and UI real estate for thigns that are no longer relevant and the game slowly turns into cat and mouse trying to find what was relevant.
