Not too bad, after all.
Well, I won't give it a 10, but it was a good story. Unfortunately, they seemed to miss the obious hole in his story...The first time, from the previous ep, he woke to find his girlfriend dead. Now, he woke up, left, and returned to find her murdered? The other thing is the letter is still a plot hole...if they were fighting and he shot her, I doubt highly that she'd sit there and write a note like that...
But! I'm glad you took initiative! Pheonix Wright is an awesome game, and I'm hoping to see more games like these and less parodies.
