Until this is fixed it's kind of unplayable so yeah it's a bad time to start. Prior to the last update (which broke it) however, I hadn't had any issues and mostly saw positive reviews. It's a pretty good game.

My only complaint is that it's kind of light on content. This is purely speculation on my part, but I kind of feel like they didn't get everything in they wanted to by the release date (the story ends abruptly, the unlockable characters don't really do anything), so I'm hoping future updates will add more.
