Not portable; Leaves registry key and folders behind.

"AppData\LocalLow\Thaumiel Games"

"HKEY_CURRENT_USER\Software\Thaumiel Games"

Thanks for checking. I'm sometimes not sure about the distinction between "portable" and "no-install".

the registry keys are whatever options you change in the menu,
and the app data folder is Unity game-engine junk.

If it saved menu options in the 'SCP_3008_data' folder
it would be considered portable (just not stealth)

Pretty sure any game made with Unity will create the folder and registry keys.
