You can either watch it as a whole scene all in one or watch all the scene seperately in the order you want. Each scene is looped until your satisfied ;)
Fluid 3D animation, very well executed.
I just forgot if it has sound, I might go and play it to be sure.
The only... kind of a bad point is that there is no full screen view, just window mode and even then you can't enlarge the window, its at a set size but quite a big one so it's cool, for me at least.
There are other K-ON games exactly like this one made my Imokenpi, took me a while to find them all but like I said, really worth the search and the memory size of each of these games.
The name of ther other K-ON games are: Into the Girl's school - What's wrong to be naked Hot Spring Of Tentacles Unexpected Clinic Girl's Work Let's play with the cat.
As for the site where you can see the list of all of Imokenpi's game in their english title: http://eng.dlsite.com/fsr/=/kw/RG02868/od/reg_d
