Interesting.

While my honest rating is a 5, I feel I should give my advice here. I'm not trying to sound like an asshole or anything, I just feel you could've done better, really. Maybe some sound effects where hits were taken. Maybe a song that fits better with it would help, too. In example, the song you have there doesn't even really start until after the full animation is over. You know what I mean?

Anyways, good luck. I hope to see that better version you mentioned.

Nice.

For educational purposes, this seems to fit very well. This explains the process of the sun rather accurately, and provides an example of such situations as the stages progress; which is key in an educational flash movie like this. Here, have a 9. And good luck.

My god.

This game pissed me off in so many ways. This is a good concept. Good luck.

Excellent!

Another display of Gameplay > Graphics. The gameplay reminds me of a minigame from Yoshi's Island (SNES) which is exactly like this. Did you perhaps get some inspiration from that and incorporate it into this?

Excellent submission. Good luck in the contest, and good luck in the future.

Challenging.

This puzzle-ish game is... fun. That's all I really have to say. Fun and challenging. Good job.
