It's a game. That is for sure.
Firstly, it could do with some instructions (controls?). I'm guessing this is just a one button, platform jumper. Though the yellow thing that darts off away from you at the start of the game confuses me. Am I supposed to shoot it? Catch it?
You really need to add a home page which could link to an instructions page maybe credits (makes it look a little more professional) and a start button. Then think about more advanced stuff like collectables for points as well as earning it through distance.
