First of all: Whatever the name of the game really is, it isn't Silk. As you see on the title screen, the name consist of three characters. Silk is written with two characters that look quite different. But Silk is the name of the executable, and few people outside China can read Chinese letters, so it is just natural that it would become known under this name.
Silk is an erotic Qix clone. It has more than a passing similarity to the first of this genre, Kaneko's Gals Panic. But I don't think Gals Panic has dancing hula girls when you get 100%. If it has, I have never seen a screenshot of that.
Technically, Silk is surprisingly robust. The oldest computer I have played it on is a 10 MHz 286, I don't know whether it plays on less. It played just as well under XP, but I had no sound, even though my mainboard emulates a Soundblaster (that works, for example, with Chasm: The Rift). I even tried setting the BLASTER environmental variable, but then I don't know what exactly I would have to set it to to match the mainboard emulation. Since the sound is mono, it's also possible that it's really AdLib, which is emulated by most Soundblaster cards but not newer mainboards. So DOSBox is probably the better choice. It plays without problems there as well, that's how I took the screenshots.
