Short and to the point, I just wanted to thank the creator(s) for making a linux release of this game. I only had a minor issue with launching on archlinux, had to set TERM=xterm, which was/is a mono-related issue.
Great game so far! Love the DRM free. I will tell my friends.
Typed from my GPD Win running linux (so you know that means love),
PS) Celeste should be on GOG!
