You asked for a save function previously right? Well, it was a lot but I just uploaded the new final (final (final)) update, it now lets you export and import saves regardless of whether you are in the installed app or if you opened through the html.
Changes:
-Improved zooming in and out in the code page, now it is only slightly laggy compared to how it was previously
-The issue that forced you to click the stats menu twice in order to open it after leaving it with the Return to your Quest button has finally been fixed (this time for real)!
-You can now import and export saves, this should work regardless of device and be compatible between them.
As always, I will update my modding thread shortly to point out which files have been changed so that anyone interested in modding can update them to the latest version.
This changes are save compatible with the last version, as no scene files were modified.
