Right it was okay.
I feel that there is a lot wrong with it though.
Firstly, on the loading screen, with Kai grinning and a light shining over his eyes... You notice the white dot flicker above his right eye when this happens yeah?
Now that might seem like a tiny detail but these little things persist throughout the whole flash. It's like you just need to go round and polish certain bits of animation.
I can understand your desire to submit this after working on it for a year, and well done for the hard work you've put in, but you shouldn't ever settle. Don't be content with a piece of work that you know you could make better if you made that final push, rather than limping over the finish line.
The voice acting was good, in that it was believable (sort of), but the quality of recording let it down.
At one point, Kyle's voice simply stopped and we were left with subtitles to explain the story (about how they have to guard the territory for the 3 bosses, or something). I see you've kindly written that bit of dialogue down in the Author's comments, but why is there no voice acting for that part?
The animation was okay, I can tell that a lot of effort has been put into it, and as you use flash more, you'll discover and develop techniques that will allow you to do so much more with seemingly less effort.
This pieces gives off a "Work in progress" feel, and I can't really give you a fair score because your hardwork has been undone by untidy animation and imcomplete dialogue. The plot is fine, I mean, it's interesting and I look forward to seeing how the story unravels. I just want to enjoy it, and not feel like it's a chore to watch.
I really look forward to more from you, keep up the hard work.
