Has huge potential, needs more gameplay mechanics. I would recommend turning gold into an upgrade resource. Increase diffulty, by a LOT. Crafting and Inventory could easily be done in the same UI window so you can do everything in one window. Factories should probably be more expensive power-wise.

Needs polish and a lot of tuning, and then it could be something real special. Truly an unpolished diamond.

It definitely needs some work. There's a broken stacking damage effect between Stars, Frozen & the Sword, I'm currently up to an indescribable amount of 0's. Bones collected UI left my screen ages ago, and damage numbers are nearing the 10th line.
