I thought this was one of the best FPSC games I've ever played... you just need improve your skills in some areas (and get a better microphone!

). As everyone has said already, I really loved the custom animations.
The most annoying thing for me was the first platforming section; I actually wasn't even sure if I was meant to go down there because I died so easily (and I died 4 times before managing it). The only redeeming feature of the platforming was that it was consistent, so even though I had to jump waaay sooner than is normal for FPS games, at least once I'd worked out when, I didn't have to work it out again.
And while I do have a GTX 560 (so I wasn't exactly
expecting bad performance), I was still pleasantly surprised to find the game ran beautifully smoothly the whole way
As others have mentioned, the sound was a bit lacking... I mostly gave up on the story by the end because I actually couldn't hear the voiceover
Overall, very, very impressed with the work you've put into this, and I can't wait to see the next episode!
