Not much reason to bother with this one. The Engrish is bad, the story is nonexistent even for a porn game, and even the sex scenes are boring and drawn out. The absurd sex poses may be like they are for laughs, but I kinda doubt it.
The MC is interesting in appearance because she's only good-looking, and either is scarred from past adventures or there was a glitch in the rendering - I prefer to think that it was intentional. The alien is absurd, maybe deliberately so. That tiny loincloth hides a dick that must have been folded four times to fit under there.
I can't tell how seriously the devs wanted me to take this, but even as humor it was still boring.
