Fun, but needs some more variety
I liked this, its pretty fun, for about 2 minutes, then it gets old. I think you need to give it a little more variety of pieces. Also, a selection of music would be very handy (because I don't really like the song you used - just a personal opinion). Also, if you know how, having an option to export to a jpeg would be awesome. A selection of default faces would also be a nice improvement.
Good luck with the full version, I am sure it will be awesome.
