Saw this video yesterday for the enchanting Flight of the Fireflies app from Woolly Robot. I downloaded it last night and spent a blissful half hour drifting around a collection of twilight landscapes looking for little glowing bugs. It's more art than game but all the same it's brilliant. Dark without being sad or eerie, time spent with this little gem of an app is like falling asleep in a moonlit forest. Buy Flight of the Fireflies on iTunes.
