You could give people a little bit of time to reply before you bump your own posts. At any rate, I have tried Marble Worlds 2, and I did not like it at all. I wrote a review for it, which due to forum policy I can't link to, but if you check out the Rusty Sabre link in my signature and go to the Quick Looks section you'll find a review for it. The brunt of it, however, is that the controls killed the game. I liked the visuals and the level design wasn't bad, but I couldn't stand the controls and gave up after playing only two levels.
Also, you might find some useful information on Marble Worlds 2 in this old thread: Marble Worlds 2
