Video:

The video animation seems to have been done with flash of some sort, the video moves along really slow, so it can take awhile to move on to the next seen.

Audio:

The dubbing is pretty good the voices where as close as they could get, but besides that nothing else special.

Subtitle:

Since it is hentai with little talking they dont use complex english words and the timing is pretty good.

Comment:

All in all it is worth checking out just out of curiosity, and to see all your favorite characters go at it.
