I loved the concept, nice and lengthy (without being shitty) and it didn't end on a cliffhanger.
Constructive criticism
The are only a few problems I can point out with this one. The voice acting is totally...egh... It needs a lot of work, I've noticed the same thing with a lot of some of your other flashes too (no offense it just seriously needs some work). The animation was a teeny bit choppy at a few parts, and that about sums it up. Looking forward to the next one.
