Oh, hi
If you can, put the plugin at last line. If don't work, send me the debug log.
Changed the Keycode from E to Space in the JS and it worked. I believe because of plugins, there will be a lot of cases where E is already being used by something else and might conflict. Maybe a way to change the key in the plugin itself might help, while changing it in the JS is super easy I know some might have problems finding how. Anyways, amazing plugin my friend, you are amazing <3
