No Linux version this time, it seems. That alone justifies a low score. Although game runs reasonably well with Wine/Proton at high graphic detail (tested on Lutris with GE-Proton-8.8, on Steam it's certified for SteamPlay), there's an important glitch due probably to emulation. And it is character's hands. There's plenty of captures and videos out there already. Considering you spend a good amount of time with hands visible on screen, it's quite irritating. So I recommend waiting for this to be solved (with either a specific patched Wine version or by developer's intervention) before jumping in.
It has the feeling of an old point-and-click adventure, but topped with great graphics. Every scene, every character and every step of the journey has its own personality. After traveling across all those places, you come to the end realising the marvelous places you have visited, the good friends you have made and the things you have learned from this universe.
