Surface EP 2 (Part 2/ 2) Really good series
I kind of wish I didn't watch it though because judging by the description you wrote, i'll never know the ending.
If it does come out, it won't be for another 3 years (each of these episodes has been released every 3 years) and i'm sure i'll forget about it.
Either way, this was truly a great flash animation, fantastic storyline and I hope it gets continued somehow.
