I think his cave titles(with the exception of Ibara BL- more of an Ikeda thing) are all fantastic, especially Pork!

I like how Ibara and Muchi Muchi Pork are both interesting twists/evolutions on his Raizing work and then Pink Sweets is a machine designed to convert yen directly into human suffering, as a prank

Ibara BL was designed and programmed by Mamoru Furukawa and doesn't feel particularly Ikeda like to me, even if it doesn't feel like a YGW game at all either (Pork meanwhile *was* codesigned by Ikeda and it shows)
