Good comic. Started out GREAT with the first three, then it crashed and burned though :(
RD's comic, the cheese sandwich comic and the Shining armor one were great. Good characterization, some nice jokes, and good art.
Unfortunately, Twilight's comic really flubbed things up. Apart from a few Lyrabon jokes, it just felt really forced, and phoned in. I LIKE the idea of the Castle being a constantly morphing sapient being that creates new rooms according to the needs of its inhabitants (And fits with the canon of the Starlight/twilight chapter book), but DANG was this done poorly.
the "lock" to open the door was absurd and situational (GOOD THING LYRA AND BON BON WERE THERE!), and the armor... Dangit price, just, that was bad :(
I Like the idea of the castle unlocking and bestowing artifacts on the six as a group for passing trials and growing as individuals, but this was done poorly.
If only they had more comics to do it in, this would have made a great 3 issue arc (Find the room, undergo a trial, break out the armor).
The Wonderbolt arc is dragged down by fosgitt's art, and sadly isn't anything memorable, apart from a couple good jokes (like the surprise one).
