Didn't have a great story, wasn't very long, and I don't think anyone can learn much from watching it. But like the last guy said, that doesn't mean it's bad at all. I liked it for its simplicity, and I gave a high score on graphics because the block creatures and the "sun", (assuming this was the object they sought) were definitely different. I've watched a few of your other cartoons and it seems like you have a colorful imagination. I'll bet you had your share of the Dr. Seuss books when you were younger. If not, it's not too late to fuel your imagination that way.
