I'm a big fan of the Phoenix Wright series and I've seen a lot of flash parodies but NEVER a fan made PW game. That's awesome! Your story is just as compelling (especially given that the crime is taking cookies from the cookie jar!) as the real game and I really felt you captured the essence of the game. There were witty retorts, sweatdrop moments, and lots of great Objection!'s floating around. Kudos to the story writer!
Of course there were a few things that I'll hope you'll fix for the next case. One of them is the sound. Since this game requires you to do quite a bit of sitting on your ass and thinking, the music is really important. I love how you used all the OSTs and official sounds but it sounds really bad when the music loops. Since you could be on one part for awhile, hearing the music constantly not match up when it loops is kind of annoying.
Your humour is awesome though and even the random Aubergines!! insert worked, I laughed so much at that (aubergines are vegetables btw, not fruits). However, the John Shaft insertion felt out of place =\.
One thing I found (that you can probably easily change) is that in the clown's testimony (I forgot the name you gave him) you spelled Bucher McGinty w/o the space inbetween the two names. Usually it doesn't matter but it made me present evidence at that point since I thought it might be an imposter (since a space would cause two user names to be completely different).
Sadly I haven't finished the game yet - I got stuck T_T - but from what I've seen this is completely awesome. I suppose the coding itself might not be too bad but I'm impressed how well you captured the feeling of the game. Good job!
I'm now your fan ;).
