I liked the first better.
It was really cool how the dude changed colors when he touched other colors. Other than that, all of the colors annoyed me and it was better when it was black and white. It needs to be a bit longer. The animation is pretty fluid, but the artwork is too simple. It seems like you should work a bit more on the artwork and make the stage more complicated and less colorful. The ending of this one was slightly more satisfying than the first.
