Not hard to push fast with this... Just abuse the bank, and store money up, while pushing sales, pushing customer money up first and foremost, keep the item prices about the same, and reset repeatedly after rushing through the initial 20 stock!
Another thought, add in card trading and upgrading! Trade in works two ways, 5 copper of any one class cards, nets you one pack of that class, and 1 copper from each class, nets you an "all classes" pack. Card upgrading is the obvious, 3 of any one level of the same type (class, skill, focus, rarity) can be upgraded into a single card of the same type, just better rarity. So 3x copper paladin 1st skill, damage increase cards could be upgraded into 1x silver paladin 1st skill, damage increase card.
Can we just screw the elevator? And let us control the depth to begin with... Cause the lowest floor is not always the best option, as multiple games have shown... Sometimes many quick runs of levels just above the lowest gives the best results, doubly so with the cards added in!
Maybe add in a small "hint" system to help people who get frustrated. And limit the number of clones perhaps? Either to critical issues, or the really important parts. They do get a tad annoying after a dozen or so trips...
Oddity, for some reason, when trying to upgrade using keypresses, it upgrades a single building, that is now at level 12/5/1 and still only costing 142 per upgrade... Weird but abuseable!
Can you add an "automatically spawn boss" option, and let the kills counter go a little higher to do so? So maybe every 200 kills, it auto spawns the boss, to allow for better idle play!
Maybe make it so traps can catch multiple Trimps per trap later on, since singles are kinda useless at a point, but catching multiples will keep traps useful (for higher cost of course)
I would remove the "All" tab since its a little redundant, maybe move the Equips to the left window, and have it replace the "All" tab (so it would be Structures, Jobs, Upgrades, Equips)

It's a rounding error it seems, but I don't think that's really a gamebreaking bug :b
