This could be a solid 4 or 4,5 for an idle-game, however let's address some issues:
Dungeon-achievements don't work
Lazy coding and discrepancies (hover over some icons and you see %S percent) and some weapons don't give the promised boost, ie. Heroic Axe of Strenght gives +224 STR (in inventory) and I have equipped a Heroic Sword of Strenght, which gives +160STR, but when I equip the axe, my strenght drops. So tweak that code better. Otherwise, I like the graphics and overall feel this game.
In short, check the code twice, let the other find errors, check it again twice and after good Q&A, put it up.
