i diddent quite unterstand what was going on. Maby add a little sound as well as more than what is their. so spend a little more time on it and it will probably be great.
Best thing I could say about this is that the sea monster's animation is pretty good. This flash has no substance, though, and the loop is glitchy because the white boxes get in front of everything after it repeats. You should look up a few flash tutorials so that you can do something really worth while.
Glitches. All I have to say. GLITCHES.
You gotta add some sound and more stuff going on, I'm sure you can do better then this.
