Since a Linux download doesn't seem to be available yet, here's how I got it to run on Linux (Wine didn't seem to work for me, as expected. NWJS never really worked well through Wine):

1. Download NWJS v0.12.0 from here (or here if on 32-bit Linux, I guess).
2. Extract the downloaded .tar.gz file.
3. Download the Same Game but with RPGMaker icon download and extract it.
4. From Same Game but with RPGMaker icon/Escaped_Chasm_Contents/Escaped_Chasm copy the www directory and package.json file into the folder you extracted from the NWJS v0.12.0 archive.
5. Run nw from the extracted archive.

I'm on Manjaro Cinnamon 4.19.32-1. Hope it works on other distributions, too.

Edit: If the above instructions weren't very clear, here's a GIF of how it worked for me after downloading the files:

Edit 2: See my second post if you just want to make a simple fix and run the game through Wine.

Thank you for this. I can confirm that this works on Linux Mint 19.1

Sent this to Temmie as well, but as she'll probably be trying to export the game for Linux there's a couple of things that won't work properly (based on exporting the game for Linux via RPG Maker MV myself):

• In the exported version there's an executable named Game that seems to be using an older version of NWJS and crashes when the Start option in the main menu is clicked.
• There's also a desktop launcher Game.desktop that doesn't seem to be working for me. Instead of the Game executable, it is supposed to launch the nw executable.
• The nw executable actually works, but fails to load bitmap fonts due to an error in the Bitmap Fonts plugin. If this isn't fixed in Temmie's export, here's how to fix it:
  • Open the www/js/plugins/Bitmap Fonts.js file.
  • Replace ",a=!1){" with ",a){a=a||!1;" to fix incompatibilities with older NWJS versions.
  • Replace "Fonts/Bitmap Fonts/" with "fonts/Bitmap Fonts/" to fix the directory in which the plugin is searching for fonts. The reason this works on other OSes is that their file systems usually aren't case-sensitive, so a "Fonts" directory would be treated the same as a "fonts" directory, unlike on Linux. This also most likely fixes the crash when running the game through Wine.
  • Edit: If you're having issues with the custom font not being shown upon the first load of the game, additionally replace "return a}" with "ImageManager.loadBitmapFontImage('GameFont', t.meta.image.slice(0, -4));return a}".
  • Save the file.

I just used the default "games" enviroment of bottles, it worked flawlessly

Hello. Linux user here. I wanted to say that I have exported the game myself to Linux (needed to add a symbolic link but it's all good now) however I still need to work some things out when it comes to compatibility across distros. On Debian LXDE the game works just fine however when I try to run it on Arch Linux I ran into a couple of dependency issues with the web-based engine (mainly the requirement for a notification daemon like dunst and the change of certain font configurations). I am trying to work it out tho and I have told Temmie (the creator) if she needs help with Linux as I need her approval.
