As little as $1 gets you the soundtracks to HORN, Squids 2: Wild West, Puzzlejuice, Globulous, Organ Trail: Director's Cut. Paying $10 or more gets you the OSTs for SPLICE, Wyv and Keep, Polymer, Mecho Wars HD, Aliens Incusion, Flight of Angels, and iBlast Moki 2. Depending on how well the bundle does, the soundtracks for Super Stickman Golf and Happy Street may also be unlocked. I'm glad the barrier of entry is so low, because HORN's soundtrack being made by the same composer as Journey's should make it worth the dollar quite easily.
