Effort went into this and for that reason....
... it needs to be praised.
I used to make alot of flash before I moved onto graphic design in photoshop and other professional related work... but when ever I see a one man made movie of this sort you gotta give the Author some praise.
I know "Max" is probably very proud of this, its clear that time has been spent on the expressions, mouth movement and more importantly the script (something which often gets forgotten) although the graphics could of done with a change of scene, I thought it was going to open up a bit and have the gf cheating and maybe a twist like the best friend ends up going with her... but well, that would have been alot of work.
My pointers - Take some more time adding details such as shadows and tones to give the characters some depth. Try recording with a better microphone, any budget shure microphone will give you a clear recording which you can turn up because of the quality.
Great idea and well structured, can't wait to see this develop... if it does lol (I know how long flash takes)
I'll give it a 3!
