Running into the same crash as the person below, no extra information to share. Windows version works fine in Wine.
I noticed the different version numbers, so if this is something you've already fixed but haven't built for Linux yet then feel free to ignore.
The game looks excellent and the player character controls fine, but there was no challenge at all, I could just walk around and mash buttons to win the game without thinking much, so it's hard to say much about the actual combat yet, except that it looks really flashy.
Also, please add key rebinding. I'm not a fan of controllers, but I also don't like to use WASD in games that don't use the mouse.
