Can't wait for part D!
This sure ties up some loose ends, but as you said, there's a lot more to be revealed! Once again a splendid job, Oscar. I loved Mullins as character and TomaMoto voiced him brilliantly. Fingers crossed the characters (including "some other guy", I seriously laughed out loud for that one) will make it to the helicopter. Also, this one had a nice big action scene and some good thrilling suspense, while A and B had a bit less action. That makes it even better. :D
Keep it up, you're only getting better. =)
