I really like the idea
But more like to amazing cultivation simulator but idle and simpler
2D graphics where you can see your disciples gathering cultivation and so on(really simple animations or even static sprites with tweens)
And all you do is get a better sect then beat other sects on tournaments and so on
I was thinking of something like this, if i was not busy with my current project i would try to do that.
Be careful with godot tho, support to bignum is kinda weird and you should either already start with a bignum lib implemented or go for float on everything and work around the overflow.
Good luck! I think theres a LOT of potential in this one
