Installed the deb and for some reason file didn't pull any dependencies needed for install. Asked on the forums which packages needed install to run and got this as a response:

To get the shared library, you will need to libqt6multimedia6. I tested and you will need libqt6widgets6, too: sudo apt install libqt6multimedia6 libqt6widgets6. In my opinion the TMOG developer made a shoddy .deb file that didn't include the Qt6 dependencies.

I also tested the appimage available at the developer's site. It crashed Mint the first time I tried to run. I rebooted and tried again, and it ran smoothly, but used 20% of my CPU (a 20-year-old i7), but didn't report that usage. Upon quitting, my screen became corrupted and I had to emergency reboot on tty1. The third time, I had a brief black screen after quitting TMOG and launching a Mint app. Their use of Qt6 doesn't play well in LM 22.3. I will shortly remove this software from my system.

So I'll be giving is a miss but thanks for sharing.
