Not bad, I liked it. Keep it up!

The shadowed are a bit weird but that's probably because he's on the moon. Everything is weird there.

The sandcastle is a nice touch although I dont know where he got the water.

Nice Animation, Low quality sounds, No plot...
Pretty average flash "movie".

Sorry to be a grammar nazi and the movie is good but the author comment "Your on the moon, what are you going to do?", *You're on the moon.
