  2. The desire of the Amazons (transformation male in female / shemale) – You are a proud knight, conqueror of the forest, who fell in a trap. Dominant druid Cassandra forced you to serve her. You’re afraid you’re changing to a woman. If you refuse to fulfill your tasks (sweeping, cooking, shoes cleaning) you’ll temporarily be changedto an animal, spanking or a special punishment. If you refuse to wear an apron, you’ll be punished. If you help poorly with potion mixing, you’ll be punished. If your mistress wants you to wash her back and you’re feeling her up, you’ll be… :-)

The mistress of the island, the sorceress Kirke, has turned your team into pigs! She promises you to turn your men back into man after 30 days, if you satisfy their her desires. That is not so easy. Kirke is addicted to wild sex and the food can make you fat surprisingly fast. You are also afraid to be slowly transformed into a pig. But the worst thing is that you even like it. :-) 
  4. Prisoner Colony 41 Sci-fi story. The convicted hero finds himself in a female criminal colony where the job of prisoners is to teraform a distant planet.

a lot of things must be changed, in the first story, hit detection worked poorely and ennemy's speed are too fast. Level to big and no hint for orientation.

Second game, a little too répétive

I played this game some times now and i have to say the mechanics are really nice for a free game. Ok, the translation is...very basic, but the author is putting the right mood into his words.


The only thing i don't like is the time pressure. Why in hell can't i just explore the game without watching the time limit?

Remove that and the game will be much more fun!


thanks and keep up the good work!

TF Runner has come a long way, and improved greatly. Though the english translations may not be perfect, he conveys the feelings and meaning of the stories very well. Add the fact that the game itself runs much better now thanks to his work, I have to recommend this game highly as one of the better, more 'Complete' games on this site.  Thank you Sicco.

I was kind of okay with this game until I hit a pay gate for breast growth.  

Graphics are very much in the style of Avernum and it's ilk.  You can only control your character with the arrow keys and attack with Ctrl, but you still need to use the mouse for various things.  I do not have three hands.  WASD is default for a reason.

I'm not sure this game deserves a XXX rating.  I played for 2 hours and found zero sexual content.
