I just remembered some more:
Yume Nikki
Space Goose
Frolf(?)
LSD Dream Emulator (I highly suggest not emulating this unless you have high-end plugins, there's a water flashing bug)
Façade
Paradius
Pu-Li-Ru-La
Cubivore
Rhythm & Face (super blinding no matter how you play it)
There's two others I forget the titles of. One has something to do with a god or w/e named Tong-Yu...? It's a very old Macromedia-based game done by the same guy who directed and illustrated LSD and R&F.
There's also this horrifying looking PS1 game that plays in a choose-your-adventure style. It's ridiculously hard to get info. on. Every character looks like a gross zombie too
