I played it many years ago and only for a short time (the very beginning* of the game), so the details are few and inaccurate sometimes.

It is an adventure game, most likely 10 or more years old.
The character is male.
The setting is medieval or medieval-like.
Action starts in a town.*
Action may or may not start in a room at an inn, but that location definitely exists in the game.
There is a privy (exact in-game term, I believe) inside that room.
There is a woman (the character's current/possibly future girlfriend) in the town. The character can climb the wall and enter her room through the window.

* I might have loaded someone else's savegame back then, so I'm not sure about this one.

I'm sure this is easy money for someone out there, but feel free to take reasonable guesses for your chance to win. The first person to correctly identify this game for me will receive a 2,99 $ GOG game of his choice. Remember, I have no idea what it is and will have to somehow verify the information first. I don't necessarily intend to acquire/play this game, I just want to find out the name.

yeah touche, though you dont actually climb the wall i think but you use a pully system to get up. in the beginning atleast

It is Touche! I would have never remembered by myself. Now I also recall that I played not only a little in the beginning, but went pretty far into it. I knew someone would have the answer ready. Mystery finally solved. As said, first to nail it (Telnet) will get a 2,99$ GOG game of his choice.

Shogo: Mobile Armor Division would be quite good to play again after trying out the demo. I had a go at Touché a long time ago, and I do believe that you shall enjoy it.
