What is this older flash game called?

[Zero]

The background music is reminiscent of the awesomeness of megaman. You are a stick figure in a lab and you have to switch colors (red, blue, green, and purple) to correspond to the the giant test tubes that you either dive through the middle, slide under, or jump over. Of course, the first time you play, there is only one color, but a color is added on each level. After 'unlocking' all four colors, you can do an endurance run, and the longer you switch colors and dodge, the speed increases. Depending on how long you can last in the endurance run, you can unlock hats, such as: a butt, megaman helmet, goku hair, tuxedo mask, and others. I could've sworn it has 'prism' in the name, but i tried searching for it on all the old flash game sites, and nothing comes up.
