Pretty Good
The animation here was pretty fluid, although at parts, just seeing the wall as a background didn't give too much to look at, when zoomed out it looks nice with the floor and everything. That's my only problem with the graphics though, the characters look okay, I mean the style of drawing for them is pretty good.
As for the voice acting, that's pretty nice too and the singing is good, not much more I can say to that, it worked well with the animation and everything else, so no problems there. Good job on this flash overall.
4/5
