This is weird. Basically, you are a girl trying to escape from being forced to make a porno with an alien. Would that I knew what the origins and provenance of this video were. Was it really a game? Who made it? Why? Where? Email me if you know.
Otherwise, if you have ten minutes to throw into the void, enjoy. If you only have ten seconds, skip to time 5:21. The girl meets the “big, scary orange alien.”
Someone could have made a way more satisfying version of this game walk-thru. Of course, it would probably be illegal and originate somewhere in Japan.
