Mirror-Mode is working again in V20120815

Mirror-Mode preview

Among other things, the Mirror-Mode is visible again so you can play it, although I was too lazy to create extra graphics for it at this point. AFAIK It's not really a popular game mode, so it doesn't really get a high priority for me.
Anyway ... besides the mirror mode, I've also added a visualization of your score when you kill or pickup blocks. This should make it easier for newer players to notice that combos make a BIG difference in their score. Other than that I've also adjusted the volume of some of the effects by user-request.

You can find the new demo at the download-page.
