Where is the game installed or how do I uninstall it?
I use the itch.io app to manage my games, and I think I went with the default folder. And I think the itch app has an uninstall option.
For Mac:
/Users/YourUserNameGoesHere/Library/Application Support/itch/apps
For PC:
C:\Users\YourUserNameGoesHere\AppData\Roaming\itch\apps
Not sure about the default folder for Linux...
Hope that helps!
