Sorry, Linux cannot be supported at this time.
The v1.02 Patch has only made updates to the soundtrack (the game uses .mp3 and .ogg files)
I also have not encountered issues using save files from v1.01, but I do not recommend using save files from previous versions with v1.02
Also, after the credits scroll for each ending, a .webm movie file plays as well.
If the .webm movie does not play after the credits, I recommend closing and reopening the game and playing to the credits again to get the .webm movie to play.
I am limited to testing on my own PC, so anything regarding how game files are opened/accessed on other computers may not be accounted for (for example, if your computer has rules set up for playing .mp4 or .webm files or requiring write permissions to write to save files for the autosave).
