Problem fixed by running in XP Compatibility Mode. The way you treat your yukkuri and the scenerios (used by spending "yukkuri points") arn't very interesting without understanding the moonrunes.
Most of the art seems to be by Makako, so there's no graphic scenes of abuse. After looking through this game there is actually quite a bit of abuse, but its all "playful abuse" and its all in Japanese of course. Nothing graphic like the stuff we're used to. Food teasing, stepping on the yukkuri, and my personal favorite... ramming Marisa into the wall with a suii. Good times.
