There are three options to play the game. Two are bulletproof. Almost all issues come as a consequence of the third. The images will always work if they exist. Check the Images folder. (right click > properties Transfigure .97 has 1245 pieces of media and 1.39 gigs in the main folder. If this number doesn't match, redl the full version or use the alt link.
1. Download full version and play (launch in a modern browser like Firefox).
Google Drive
mega full version
2. Use the Play now / Mobile Link
You must be registered to see the links
3. Download the upgrade pack (which is not the full version) and apply it to the previous full version.
I hope that helps.
Edit: I realized you linked to a discussion about Android use. Android instructions are as follows:
1. Download game on phone. (You can unzip on your phone or transfer the already extracted files to your hard drive)
2. Download the latest version of Firefox for Android.
3. Main screen > My files > device storage > (wherever you put the game) > Transfigure by Tango > hold finger down on html /select it > click on ... top right > add shortcut
4. Launch shortcut with Firefox and allow permission to use the files
5. Play
Known issues: picture size varies and looks odd. Game will not play without Javascript. Some have said Chrome works on Android too but it didn't show the media for some reason so use Firefox.
