Quite Impressive.
First of all I must begin by saying this entry is most definitely underrated. When I first voted on this the score was under 3 -- it has gone up now but I still believe it is deserving of more. The artwork is very well done, and you obviously put a lot of time and effort into it. The animation and camera angles also gave a good boost to the overall impression of the movie.
The whole theme of having to secretly fight off an unknown ninja onslaught was quite humorous in the first place, but the giant gerbil and funny action sequence topped it all off and I got a good laugh out of it, for this I thank you.
The sound wasn't the greatest as you admitted in the comments, but with a lack of other voice actors and a "crappy mic" as I believe you put it in a reply to another review, I have to say you certainly didn't do poorly in that category either.
All things considered it truly was a good entry, worth watching and reviewing, so I just had to let you know how much I enjoyed it. I see said you are working on number 2, and now that I've watched this I just can't wait to see that one. Good work, especially for a "first flash" as it were. If you are being serious about your physical disability, then as corny as this may sound I have to say I really hold you in high esteem good sir. =D
