This game's dead. Last patch still didn't fix the game crashing on multiplayer.
It's obvious that this was released months too early, even for early access. When people buy an early access game they expect more polish out of it than this. At least they'd expect the bare minimal in that you can actually play it online, since it's marketed as an online co-op game.
The game is so unpolished that one of the things the hermit can do to you is give every enemy a 333% health buff. You know I would argue that it's funny that a drunk frenchman thinking it'd be funnier to give them a 33% health buff than a 30% one accidentally hit the 3 key three times, but it also gave the Door boss such a ludicrous health pool that my results screen looked like this. I only stuck it out because I had the flower alchemy so everything taking a year to die was only a mild annoyance. Except for the door. That fight is so bad I'd rather they just took it out of the game.
