It's still loaded with crashes for many users. The developer has ceased support and the game isn't quite done. That said, MOST users only have minor issues.
I HIGHLY recommend that if you buy the game, you get it from Steam. They have an easier return policy if you do run into issues. I bought mine from GoG and I basically had to publicly shame them to get them to honor the return policy. I haven't purchased a game from GoG since as I'm still a bit miffed over that situation. I will purchase again, but only games they offer that I can't get on Steam/Origin.
Ceased support for the game itself or for the GOG build only? Because I bought it as soon it spawned here...
