Dementium is an alright horror game, Dementium 2 refines the gameplay and the horror elements a bit more than the first.
Barnyard Blast: Swine of the Night might be one to check out. It's a Castlevania parody game with a handful of references to old games and some silly humor. The gameplay isn't fantastic, it's very old school in design, much like the older platformer games that it has parodies of. I'd take a look into some videos of it, but it could be something you find entertaining as an overlooked DS title.
