Created by a studio called, of all things, Taco Graveyard, Penumbear combines light-based puzzles and a platform adventure game into a very good-looking mobile experience. Playing as the aforementioned bear, you find yourself awakened by a color-changing firefly who leads you out of the dark castle where you dwell. Getting from dank cellar to sunny field is going to be quite a feat, though, but luckily you have a very special ability involving lights!
