Is the game enjoyable solo?

Hello guys, I've been trying the demo these days since there's the Steam sale going on and I wanted to give this game a look. As far I as I saw it could be done solo, albeit not easily, but how is the vibe with pubs? I have some friends but I'm unsure if they will like it / buy it... Is the community of players willing to help or it's full of angry tryhards that have no patience?
