Pixeljam has made its feel-good dinosaur racing game free to download today and tomorrow. You can grab Dino Run SE on either the Mac App Store, or from Bandcamp, which is also home to the newly released Pixeljams Volume 1.
Anyone who is a fan of dinosaurs or dinosaurs wearing hats ought to download this game. I can only imagine that sentiment applies to 99.9% of our population, so get to it! If for no other reason, partake in the generosity for those excellent tunes.
