Interesting take on stealth. It's good to make the player act cautiously, but in this case, I only acted that way because there's such a small gap between the left side of the screen and my hiding place. Effective, but dull.
I *think* different types of people give different amounts of money, but it took a bunch of trial and error just to guess that much. Average Joes only give about 50 bucks a kill, and the king gives 100-150 -- if he shows up. (I got over 100 from an old lady once -- what did I do, steal her pension?)
What's more obvious is that the economy is shaky. I don't have enough hours in the day to pick my targets, and mugging any random person isn't nearly profitable enough when I can make maybe 4 kills at most, I have to spend 250 plus 50 per bomb, and I need a bomb for each kill.
That last part's the worst. You might want a reset button for people who make the mistake I did: not knowing that smoke bombs were mandatory until I tried to beat day 2 with only a single bomb left. Now *that's* an ambush.
