The music wasn't done by me but by other contributor (chiptami), I was doing all the programming and art. You are quite right about having a hard time seeing the faces, and I wanted to implement a "face ghost" to better see what face will appear in what direction, but I just didn't have enough time, after all, my time management skill isn't quite splendid. There wasn't much time sadly spent to making levels as well, as I needed to make all the menus and all the other 'tax work'. In fact the game supports multiple dice and has a rotation block, but it's never used, except for rotation block which is lazily put at the end, and at the test room. Thanks a lot for the constructive review.
