Darvond: What I recall is that in the demo, you could press keys 0-9 to switch various scenes and the protagonist being female was able to grow wings or into a mermaids form at certain trigger points. A cavern area had a particularly distinct and repetitive drip loop for ambiance and the CD came with a texture viewer too.

The worst part is, I used to know what it was called, but I have since forgotten.

I also recall it was from a Diamond Stealth, but I don't recall the model either.
