I'm a fan of diceless games for practical reasons: I do much of my gaming these days on a commuter train. The choice of diceless play in Solipsist is more of an artistic one - it's a bit too light for some of my group who like more crunch and grind to their play style. Fair enough, yet the simplicity of the characters and the resolution system work very well for me. I especially enjoy the idea of overshooting a target number being about as bad (but in a different way) as undershooting it.
The artwork is entertaining, but how bidding works could have used a graphic explanation as well. Nothing major would be needed, but would be useful.
All in all, a great little game with some big ideas. An excellent value!
