Kumatanchi is a raising simulation game for the DS currently in development under Dimple/Vanillaware (of Odin Sphere fame). Basically you play the role of a zoo keeper who's looking after this bear called Kumatan and you feed her and take care of her for two weeks in real world time, the game will continue even when it's switched off. The game is currently slated for release this summer.
The thing about the game is that it is actually being developed by the doujin circle Ashinaga ojisan, the guys that made Habanero-tan house, which is very similar in concept to Kumatanchi. The artist in the doujin circle is actually an employee in Vanillaware and has worked on Grim Grimoire and Odin Sphere, so that's probably how they got their chance to work with the company.
