Hmm
The animation was good, and you did a good job using the sprites. As a sprite animation it's pretty good, and I like the style you used.
Don't take this the wrong way, but I think the Sonic and Knuckles being gay thing was a bit tough to watch. I'm not atall homophobic, but watching Sonic and Knuckles - two pretty bad ass video game characters being all soppy and in love with each other was a bit disturbing =/
