For a three week game it's great, so don't fret about that too much. That said, every game from the event has it's bits and bobs that need a bit of work. Not a one is perfect!
(Even though I say that I've yet to play any of them yet but I know it to be true because no game is perfect and I'd be surprised if any of these ones were too. ^.^ Great for what they are, yes. Perfect, definitely not. There is not such a thing.)
I mean, if the worst someone can say about the game is that the slow walk speed is a bit annoying and that the intro needs some work, then, well, that's nothing much to worry about! Easy fixes~
