Is it fun to play solo?

Greetings! This game has been on my Steam wishlist for quite some time, and I wanted to buy it before the sale ended. However, I’ve read in the comments that it’s better to play with friends. Since I don’t have any friends who play this game and I’m unsure if it’s enjoyable to play solo, I decided to postpone buying it. Now that I’ve joined this community, I wanted to ask: Is the game fun to play alone?
