Here's the walkthrough from earlier in this thread, in case anyone has lost it:

A simpler restatement of the above walkthrough points, for the English version.
* Lust-worm first gets "stuck" at 49% until a masturbation event (next sleep). Next is 79%. Finally, 100% causes a game-over scene.
* If you ever run out of time, the fortune-teller will rewind time for you.
* If you survive 15-rounds in the first fight, you will have an alternative first scene and remain a virgin. Otherwise, it is gameover rape.
* Once you get to slave-city, you can talk to the fortune-teller whenever you get stuck. She'll tell you where to go.
Early game:
* There are two goblin loss scenes. It seems like losing to exactly 2-goblins will always trigger the non-loss scene (torn clothes + rape, but still survive).
* Visit bridge, get blowjob request. If you do the blowjob, get a scene. Otherwise, you can try to swim across. Swimming will cause a fight scene with an octopus, which has a game-over rape scene.
* Desert worm requires a level 4 spell: Lightning. Cast Lightning on yourself to kill the "little worm". If you cast lightning on the big worm, you will be bound by the "little worm" and lose.
City-wide Slave Port Ishtar events:
* Visit the bishop four times for 4x scenes (leading to a game over)
* After playing strip-blackjack with the cheater, visit the harbor / docks. One of the NPCs will give you a normal deck of cards, and you can play non-cheating Blackjack to lower the cost of the slave-broker.
* 4th fight in the arena is against the Lizardman. If you beat him, his trainer gets angry and offers you the Lizarman as a slave for $80,000. You'll free the Lizardman, but he'll give you an item to summon him as a 3rd party member.
* Half the prostitution events are for high lust-worm progress, the other half are for low-lust worm progress. I don't know the precise cutoff, but assume ~80% for some events, and ~20% or less for others.
* There's a virginity prostitution event.
* The "Street Stall" in the harbor will offer rare items as long as you have the Hunter's Mark equipped. You can get the Hunter's Mark by getting 10-wolf pelts to the injured man at Balsa Winds (Overworld)
* If you need money, Dancing is an option (and retains virginity). Prostitution is okay, you probably can still get 10k+ per time-unit at the Arena however.
* Some prostitution events seem to only come up if you "Approach Someone".

Hmmm... that's a lot to type up and organize. Lol. Maybe I'll work on this more later...
