I like the game. A feature request would be to have followers be able to auto-sell things, maybe to balance it you could have them auto-sell at like 60% the actual value. Would make it a little more idle friendly.
Allow me to buy Base damage with gold, so once I've purchased all weapons, I can still use it. It can be like 5000000000 for X amount of Base Damage, which means I'd buy it after the best weapon, but my gold wouldn't be useless at the end.
