I love it!
that is very good movie!!
it is cute as well as its cool!
the animation is really nice and very well drawn!
i think you should make it longer by showing more attempts of the blue square guy and his red square buddys reaching to the sun!
this movie is very original, and i, personaly really like this prehistoric stuff... (i hope i got that right and that was really a pre-historic tribe... *the campfire and the wall drawings)
Your movie have a great potential! Keep it coming !!!
Great job!
