Ok, actually took the time to play it and explore, it's a brilliant concept really. One thing bugs me though, that sometimes the mutations are..... TOO weird. I can enjoy the thought of a Niko with maybe wings instead of arms, but when it's something like that demon mouse you find where the catnip is, where her clit is pretty much half her size (at least that's what I remember that's what it said) that's just disgusting. Said it took up her whole stomach or something.
Also, if you infect other people with sex, it's always the same description except when doing it with a guy or girl ((ugh, apparently I did a guy named Lisa. Damn mutations...)) So it's rather bland in the sex department. Only time things got detailed were when you read that magazine. The endings were also quite short. I didn't find myself aroused by this game really.
