Who designed a level with 6+ minutes of timewasting before an extremely difficult scenario involving negotiating three different people among killer aliens... and then gives it a strict time limit?! No wonder the leaderboards show 54 people completing situation 16 and only 19 completing 17.
Finally completed after who knows how many tries with 9'37"03... and I get an 86/100.
Phew.. just needed to vent.
