Erm...
How do I put this gently... it stank like my dog after going 8 weeks without a shower. And my dog is always like that and he stinks. A lot. There was no story, no voices, and nothing but SuperSonic flying around (with a box around him), then turning into Sonic and falling, then going Super again and falling! What was the point? And wait, when you put Sprites into animation, don't you learn how to get the boxes off of the sprites? You really need to go through that again and get those boxes off of Sonic! Anyway, since this is your first Sprite movie, I give it a 4/10, 2/5.
