I lost after the second day when apparently something caused my money to drop by -40,000. I honestly don't know which mission did this. I had one mission that looked like it might have been a failure, but maybe it was a success the description was unclear. The others read like successes, but maybe they also ended up costing money. Again it was unclear. So yeah, I just feel like it needs to give more feedback on what worked and what didn't. As it stands it mostly just feels like I have to use trial and err...

what is the email to contact the devs?
