Has anyone tried this out yet? I'm curious about it, I may have to buy it myself.

I watched a few Youtube videos on this...it looks like it has some serious potential.

Played a bit of it recently. I kind of like it, though there are several moments where the character seems to move too fast and you want to throw your mouse in frustration because she approached a gap faster than you would've liked. If you have $9.99 to spare (and surely you do because you're on GOG) and are willing to try something new, pick it up.

I played the demo on XBLA briefly and freaked out when I heard the Swedish nursery rhyme "Byssan Lull" being sung in the background while on the title screen. Did NOT see that coming...

I really like it and will be buying it next week. I can see it being a bitch to get all of the fireflies but it'll be good
If you can imagine a strange combination of Lemmings & Tetris you're sort of on the right track

looks a bit interesting, but I can see myself getting bored with it too soon.

In case anyone is interested: D2D has SecuROM activation requirement.
I'd imagine other places have a similar setup.

Seriously? Ugh

It's also scoring some pretty average reviews. It seems like they didn't take the time needed to really polish the gameplay.
