I think this game could benefit from a "gold per hour" stat on each level based on the DPS. That way we can figure out what stage to stay idle on easier. Not essential, but it would be nice.
Defeats High-tech Robot, loots cloth armor and a stick. WINNER!! Also one thing that could make the selling of items easier is a Sell all button or something like that. I constantly ended up with a full unused inventory and had to click and drag soooo many times. just a minor fix. Otherwise awesome game! 5/5
