Kinda wondering why not simply use Ren'Py built in translation tool? Lots of errors occur when you translate from English to Spanish then back to English...
- Replaced 'game\tl\None\common.rpym' with the English version.
- Edited 'game\screens.rpy' as a few options either weren't translated or poorly so.
- Added text outlines, ability to set textbox opacity, and toggle the quick menu.
