We've noticed an influx of bug reports regarding controller detection. A potential fix for Windows has been uploaded. If you've been having controller problems, please switch to the 'next_update' branch and see if that addresses the problem. Mac and Linux builds will be uploaded soon. (Edit: Mac/Linux builds are now live)
If you're still having trouble, please send an email to email@example.com detailing your OS and which controller you are using.

Right click on Hyper Light Drifter in your Steam Library
Click on "Properties"
Click on the "BETAS" tab
Click the drop down menu and select the 'next_update' branch
Click the "close" button and your game should start updating immediately
