Yumi's Odd Odyssey, as a franchise, has always enjoyed a full retail release in Japan. So when it was localized for a whopping $30 over in the states as a digital download, more than a few people were less than happy. Starting today though the price will sting a bit less, as it's been lowered to $19.99 until June 15th.
If you're a platformer enthusiast, I highly urge you to pick this game up. It has a pretty amazing and open physics system that allows you to complete levels your way, and the designs themselves are taxing enough for any hardcore fan.
