Oh hey, I played that. I'd played some other IntiCreates games that were fine so I gave it a shot.

Thought it was a Metroidvania (it wasn't, really) with a gothic style (wasn't really). The main thing I remember other than the final boss fight being semi-lewd is that after you've found all of the female classmates to rescue, you have to go back through and find their panties.

At the time I was thinking, "I'd rather be hunting for missile expansions or something, but really it's more about the hunt anyway so if it's panties I'm hunting for, so be it."
