Sofi is a little girl who lives with her grandma, but her grandmother is old and not doing so well. Sofi drifts into a sleep, and has to travel through worlds looking for her grandma. There are 30 main levels and 15 bonus levels which can be unlocked by collecting fireflies in the main levels. A price has not been announced yet, but Lucidity will be coming to Xbox Live Arcade and PC later this month.
I love games like these! I spent so many hours on Lemmings as a little girl, and I loved Doublefine's excellent flash game, Tasha's Game. My anticipation for this is really high now. :D
