PS3's Go! Puzzle

At first, I was play he 3-minute timed demo of Go! Puzzles Swizzle game. Then I tried Aqua, and I was shocked at how completely different it was, and difficult. Then I tried Skyscraper, and again, it was totally different from the other two. It seems that Go! Puzzle is actually a virtual console of some kind or a development kit. Skyscraper is the most original of the three, the most difficult, and it's timed! I recommend trying the demos, because the download of Go! Puzzle is free and you pay for the three puzzles. I bought the trio pack for $6.  It's priced right for me.
