Now that we have over 30 builds of the game working online, it's safe to say that game-breaking issues must be local.
If your game fails to run, try using a different machine, possibly a Windows installation with the default apps, since that's inevitably the most tested solution.
Then check your own edits
Furst of all, copy the content of your text_translated.lua, file and paste it on the https://sellaroli.com/apps/nem-translation-tool/ website. It will show you where the first lua synthax error is. Fix them one by one, then copy the text back to your file.
Then download a fresh new copy of the localization kit, extract it and overwrite text_translated.lua with your own version (to make sure no other file was changed)
Similarly, if you changed the graphics, overwrite poster_translated.png and title_translated.png inside the game.zip file. Make sure they are located exactly in the assets/single_sprites/ folder
In general, the more you can carefully transfer your edits into a freshly downloaded, stock localization kit, the more you can trust it to run like the others
Finally, zip and upload the project folder to Itch.io as explained in the step by step guide. This time, it does not need to be password-protected.
