Is there walktrough v10.0 ?
I don't think there is a walk through up to v10, but it's best to ask in the game thread for that. This thread is just for the cheat mod.
The game gives a pretty good idea of what you have to do next though. Click on the main characters picture, then click on relations, and finally click on the little images in the bottom right, they will give you a hint at what to do next and tell you if you have completed everything you can for the current version, "maximum for this version" or "final scene has been reached". If they say "to be continued" or "this is not the end" there is still more to do in this version, you haven't completed everything you can.
There are three images for Elena that will not say you have completed them though: Oil for tanning, very interesting movie, and skillful fingers. They won't say anything when you have went as far as you can, at least that is what they do for me.
