Should added yodu and nurunurubouzu because their art logo is in there?

O cool someone added it

Well, at least I learned those games are on Steam.

Except for the Udonge game but I think I probably have to blame the publisher for that for not having the English name searchable for non-English people rather than it being actually not there.
Yea, turn out the Udonge game is there under "うどんげ異種姦洞窟"
