In response to my last week's email, today I got a response from Heart Machine, the devs of Hyper Light Drifter
, here's what they said:
Thank you for reaching out to us. Updating the GOG version of HLD is certainly on our radar and should be coming quite soon!
Thanks again for the feedback and insight, please feel free to reach out as needed!
It's always nice to get these kind of responses, hopefully they will follow through :)
