PSP Disgaea side scroller, Prinny: It's ok if i'm the hero, dood?Release date: Nov. 20, 2008
Cliffnotes:
-Etna's dessert got stolen, she gets pissed off, sends you off to find the ultimate dessert
-10 stages, 6 stages available at game start. Difficulty and gimmicks change depending on time of day.
-Time advances at the conclusion(i think?) of a stage
-Prinny can spin (horizontally, vs sonic's vertically and sounds like it functions similarly), jump/double jump, do an ass slam, throw, etc.
Preorder bonus will be a soundtrack by Satou Tenpei
