Did a bit of a search for info, and I found out that the same people who made this also either made or are affiliated with the same people who made Grief Syndrome (I'm not sure which, I don't read moon). Either way, it can be found eventually
here. Note that the picture in the OP is from New Super Marisa Land. (It can get confusing as there is Super Marissa World, Super Marissa Land, and New Super Marissa Land, so be sure which one you are getting)
