Yeah, it's totally the "Naples" font from DeluxePaint.
(I really need to make screenshots of all the DPaint fonts one of these days. I even managed to sort of reverse-engineer the font format and write a script that renders all the characters...)
I could've sworn there was a video of the game's ending sequence on YouTube, but I can't find it-- anyway, all the credits are Gamtec-affiliated folks, including Hong Ji-min and Lin Cui-e. (Edited to add: The Chinese characters for the credits can even be seen in a tile editor, albeit somewhat scrambled around, at location 0xC4890. This is how I confirmed Hong and Lin.)
