If you could give more details about your config, the output etc it would maybe give some hints. Also you can look at the log in ~/.config/unity3d/adamgryu/A\ Short\ Hike/Player.log.
I am using Debian unstable on Sway (Wayland) and Mesa 20.1.1. On Wayland you need to unsure to unset SDL_VIDEODRIVER because the Wayland backend does not work well. With this config the game (amd64 version) works like a charm :-).
