When going up the stairs I cant see the broken mug. So this guide is useless.
My walkthrough was for the previous train version 0.2.
The newest one hit today and is 0.3. A lot of things changed. Locations for items were changed what item you got from girls also changed so yeah can't really use it anymore.
Edit : Some of it is still good . For example what you need to give the girls to make them fuckable is still the same.
All of the items are still in the game and what items to combine is still the same.
Only thing that was added was 2 items (sword and the scabbard combine these 2 and give it to the new girl in the last train compartment)
Edit 2 : And also a key was added to unlock the last train compartment. In 0.2 you didn't need a key but now you do.
