I checked the developer's ci-en and it seems someone found the solution for the crashing that can be used for 1.00 version of the game. The idea is to update the nw.js used for rpg maker engine.
-Go to
You must be registered to see the links
-Download the 'normal' package (it's a zip file)
-Unpack all content in the zip and put the files inside the nwjs folder into the game folder, overwrite anything if needed
-Open the package.json file inside the game folder and change the following line:
"name": "",
to
"name": "{}",
-Launch the game using nw.exe instead of Game.exe (it works with mtool)
Played for a couple of hours without crashing.
