LucasArts debuted their original game, teased a few days ago, tonight on GameTrailers TV. While it’s not a full retail title, it’s quite an impressive looking Xbox LIVE Arcade game. Lucidity is a puzzle-platformer where you play as Sophie. Sophie’s grandmother is getting old, and these dreams she’s having are usually about Sophie looking for her grandmother. You don’t control Sophie; she walks no matter what. What you’re doing is placing pieces down in front of her to guide her through the level safely.

There are thirty story levels and about fifteen bonus levels to complete. The guys at Lucas said they’ve definitely gotten inspiration off of games like Braid, etc.

Lucidity hits Xbox LIVE Arcade later this month. Stay tuned.
