While I am only partway through the first story, it's a pretty solid one so far. Grammatical issues are few and far between, and the story doesn't take itself overly seriously.
The story itself seems to be similar to "The Open Door," with the attitude of crossing over into multiple universes and having shenanigans happen as a result of that, but it lacks the Base Breaking actions of "New Chaos" that seem to have doomed that story. The majority is upbeat and fun, and quite enjoyable. If you have an afternoon to spare- and you don't feel like doing anything else- I'd give it a shot.
