Okay so I've tryhard the game a bit and I defeated a few gold golems but I still couldn't reach the 800 gold quota. Also something about the UI that I didn't understand at first is the fact that there is no unit for the quota nor the reward whereas for the level-up requirement it is specified that it is gold. So at first it is not obvious that they are all in the same unit. And maybe to make it more clear write "commission" and the % of your cut, on top of the value in gold. I still thinks the game is great, although a bit addictive and too difficult in the end.
