The PC version of the demo project should be able to support Linux. If you look at the downloads, you should see a Tux/penguin icon - marking it as Linux-compatible. Ren’Py as an engine has Linux support by default.

Standalone .rpy file will work on all supported operating systems.

It should appear if you right-click or press Esc - it’s part of the pause menu.

The reason why it throws an error is because the current_room variable is set to None and that there’s no list of buttons called None_buttons

To be a little technical, the plugin tries to load buttons by looking at the current_room variable, adds _buttons to its value and tries to load the string result as a variable.

If you have a list of buttons (in the correct format) that ends in _buttons (ie. bedroom_buttons), the current_room variable must be updated to “bedroom” before jumping into the pnc_loop label.

The license - if any - would simply state “feel free to use it in and modify for your game, just credit me”

I’ve deliberately made the plug-in barebones even down to the graphics, so that people can customize it to fit their games - including persistent variable support.

I don’t mind it being in your blog. In fact, you’ve made it easier for Japanese developers to work with my plugin (including your modifications) now that they have documentation for it in their native language, so I support this.

TL;DR - I support this, thank you.
