The full title of this is Starman: Tale Of Light, apparently. I used to think the little person in this was an astronaut, because the title is Starman, but looking at it again it could also be a beekeeper. Or possibly a lepidopterist, because the lights you collect turn into butterflies.
It's a very slow paced game, this. A puzzle game, where you must find and collect a little ball of light, amidst the ruins of... something. A civilisation, maybe. One place looks like an abandoned fair ground. Or an old cruise liner. Doing so involves, often, moving light around, in a cube, or through little portals.
It's not so hard that you'll throw your keyboard across the room, but it's not easy either. It's very good, Starman
