Hi hogtrick, thank you for the feedback! That would be quite hard because that means you need to encrypt your Json file and decrypt it as you parse it in GMS2. For saving the game you can follow many tutorials on YouTube, especially the ones who use buffers.

Thank you for the reply. I think I found a solution for my case in particular that add just enough protection from curious players. Zipping the text file and changing the extension, then unzipping and renaming at runtime, also everything would be done in appdata folder and not the game folder, I think its good enough.
