I don't plug in my controller, I have an adaptor, so does that mean its not adaptor compatible or something?

Talk to me on discord, im GM Hadok. So I can help you make it work:

You can use free app for games without support. Antimicro. It's open source, safe and easy to use program. Download directly from GitHub, install, and run as administrator. Configure keys, and play. 

I might not be able to do that due too... personal reasons, but its not a problem tho, I'm fine with using the keyboard.
