Heavier games usually made by bigger teams that can put more resources to the game optimization :(
Nevertheless, next game release will be much more memory effective so keep an eye on a project
Just remembered that this game exists and can happily say that the newest version runs flawlessly on my PC with the highest settings. No idea what was wrong with the old build but I'm glad to see my computer wasn't the issue and isn't simply too weak to handle it.
Great game from what I could tell with my first test. Will look into it further.
