'ORBB - A casual, relaxing, and challenging ethereal space experience game' was temporarily free this past weekend. Unfortunately, it's back at $.99. The object is to jump from planet to planet and catch all the stars.
What I really like: you can never die in this game. There are 60 levels and I've done 47 of them. ORBB is definitely cool. ORBB was designed by Kyle Yamamoto & Howard Go.
Update 3/24/15: I solved all the levels. Good fast & fun.
