Beat this without getting sex'ed. The girl is safely teleported home, then she says something like "I don't want this kind of experience ever again", and with that I agree.
The game is fairly easy, losing (getting raped) is not obligatory (nice), the gallery opens after finishing the game, even when no sex.
Sprite animations are ok, not the best, could be better I guess, just ok. There are just a few poses shared between different enemies, and no many different angles of the girl. Games with a wider variety of animation poses exist.
CG animations are "ending videos", you can't speed them up or have any controls at all. Start scene, skip scene - that's all you can do. So you are stuck for like 15+ seconds here waiting to see the penetration, then it goes on for some time, then it stops.

Overall I'm just glad to finish the game without engaging into sex with her. The gallery is enough.
Just save your time - download the save and check the gallery.
