Like in the first game, you play by selecting shapes from the menu at the top of the screen with the mouse, then placing them somewhere on the screen where they won't immediately fall into the abyss. TAKE NOTE: You can rotate blocks with the keyboard, using either the [Arrow Keys] or [A] and [D]. One welcome new feature lets you return a block to the menu if you change your mind about it.
I can't honestly say that this is a soothing experience, despite the (sarcastic) sounds of waves and birdies in the background, but I can recommend it as a method of teaching yourself to handle stress. If you can handle this, then staying cool during an avalanche should be a slice of pie. Just remember what the game tells you: RELAX! TAKE A DEEP BREATH! RELAX! RELAX! TAKE A DEEP BREATH! RELAX!
