Alright. There's a few more bugs.
The stock profit % achievements are entirely broken. I have 6000% on one of them (due to power grinding cash...)
The weapon fusion can be entirely positive upgrades but give you a -90% compatibility.
But other than that, great game. Suggestions below...?
Synthesising weapons, maybe. Entirely destroy weapons to make new ones of the same type. Oftentimes worse, but usually for the 'Jackpot Effect' where it is MUCH better.
Descriptions for the stats. It took me four hours just to figure out which stat sped up reloading and how many points would it do so. PLEASE put something like that in it.
Shotguns should have an ammo attachment which lowers the ammo capacity, but increases damage SLIGHTLY. e.g. 2% damage increase for -50% ammo. Trust me, it's worth it.
It'd be nice for all the stocks to start out on flat lines, so you have NO idea what to buy or sell until later in the game. Otherwise, I can just get my best items from the previous game, and get over 300,000 in coin, and get 800,000 back because emeralds were so dang cheap when i started.
And uh, the 'painless' acheevo is really easy to get if you die.
A lot.
