Hey thanks a lot for all the feedback. Most of what you mentioned will be fixed, except for the mountain size, at least for now, I mean, it's a fictional mountain in a fictional world after all. As for the Idle distinction, that is actually a good point. I might reconsider the name going forward if players think it's misleading.
The save is a difficult topic, since the game it's still so young, I'm sure I'll have to keep breaking stuff between major updates, but I will always try to keep it compatible where possible.
