Klei eventually delivered on the GOG version, and honestly I still like single player Don't Starve even if the multiplayer version (not on GOG) recieves more attention; games are good by it's design not by update quantity. If you want mods search "Steam mods downloader" and pick a website, then just install the mod on the "mods" folder inside the "Don't Starve" folder. That's the solution that worked for me.
After 150+ hours in the game i can certainly say i had a lot of fun, however the game is not without its flaws though i find them mostly torelable, aside from the technical flaws that others already said. The best parts of the game are the battles and the mech customization though they go hand by hand. The game has a lot of mechs, 60+ if you count the variants (and you should) each of them are completely customizable, you can change the amount of armor is fields, what weapons it has and because of that the role of the mech . It is really fun to get a mech and think of the many modifications you can make it and is really gratifying to field your personal build and watch it blow up other mechs. This is definitily the best part of the game for me. The battles are also really fun, because we are talking about mechs there is not many ways to avoid getting shot, cover only reduces damage and only the fastest mechs can get enought evasion to make the enemy miss, because of that the game revolves around tanking hits, tumbling mechs with stability damage, and destroying the body parts that have low armor. How you build your mechs is key as is how you build your mechwarriors. The flaws lie in the repetiveness of the missions past a certain point, as they all tend to devolve into straight battles with the objective of the mission being abandoned in favour of just killing all mechs. The game also has a giant map which however feels lifeless do to lack of lore, events, or even noticible differences between systems and factions , you basically can spent the entire game in the same sectors and it won't make a difference. The story is decent and has the best missions, however they are nothing to impressive and the story while solid in my opinion is nothing too amazing, the characters also lack depht with few conversations in the campaing and few interactions in events. The game also has events à la FTL which while supposed to spice the time between missions tend to mostly repeat themselves.
