Freaky Forms was originally a strong creative eShop title, but now a Deluxe version is coming out on cartridge.

Seems like it may be a good buy if you havn't played before, but may not be really that much more if you have. Also, the eShop version is being pulled in Europe that may also happen here. If you were thinking about getting the cheaper eShop version, don't wait too long!
