There should be more depth.
I wasn't sure that you could pull it off at the beginning because of how weak the plot felt, and my suspicions seem to be right. The only thing you need is more depth. Since this is only the second in the series, barely anywhere in the plot and it says to be concluded in the next episode, it leads me to the conclusion that this series is lacking in story depth (so far that is). This appears to be the beginning of a story - a man embittered by the death of his wife due to the unbending rules of a device. The only thing is, he has to do something now or it seems almost pointless. I could be wrong though, depending on where you take this in the next episode, I'm just uncertain on how you will fit in a meaningful plot in the next one.
On the flash - great animation and graphics, voice acting was decent. Remember that the plot has to go somewhere, that's the thing you need most here as far as I can tell.
