It’s not good; personally, I would be glad if the developer sold a stable game, but unfortunately, that’s not the case.
The licensed version from Steam and the licensed version from the disc I bought at the time of release work less stably. In fact, I’ve tried many versions from the “treasure chest” of Crag Hack, but I only found one that is the most stable, and I have absolutely no complaints about it. Now I keep it like the apple of my eye.
