Thanks for your feedback and your screenshot! I'm impressed you got the arcade machine, well done!
We figured that far away contracts should cost a bit because you'd have to pay for plane tickets, accommodation and sniper gear, but hadn't really figured out how to prevent the player from running out of money completely. Some contracts in short distance having no cost would probably fix that.
I'm actually working on another polish version with moving characters, but for that to work I also need to make a mission timer expire and return without profit, which I haven't found time for yet. I'm sure I'll get an update out in a few weeks!
