quick suggestion, maybe adding in a "progress" towards achievements. keeping track of how many hero levels you've earned, or how much gold you're earned on the achieve not just on stats page.
i found a random invisible "weapon" that doesn't show up on any list, but keeps saying i have an un-viewed new weapon... checked all tabs and nothing, but still shows i haven't looked at it.
should have a 3rd upgrade option for all three tools
1- pick: increased chance the rock will produce minerals
2- gloves: area pickup with space
3- mine detector: aoe disarm (2x2, 3x3 to match blast pick at max upgrade)
 "Clicker Heroes"){kind=icon}
 "AdVenture Capitalist"){kind=icon}
 "StrikeForce Kitty"){kind=icon}
 "Minewall"){kind=icon}
Thanks for the feedback runedj159, having additional upgrades that make the mining process less tedious is a great idea.
