Choppy game-play and I think he's copying a game.

As fun as being the middle person in a human centipede.

Direction?

I had absolutely no idea what I was doing, how I was supposed to score or anything. There are no directions in-game or in the description, so you're left to trial and error. There's no sound to speak of, and the graphics are poor. The least you could do is tell people HOW TO PLAY.

The idea is good...

but not much is explained. I had no idea what I was meant to do initially and it got boring very quickly.

You need different game modes and different objects to make it more exciting and adding upgrades may make it tactical as well.

Nice idea but needs a lot more. Oh and what is it that is jumping because I can't make it out?

Good Idea, but needs work

The Idea of the game is good, but you should have added some more different objects. Like e.g. Powerups or obstacles or something. In the current form it doesnt need long to get boring.

Is this original?

Sure, you changed some of the graphics, but I'm pretty sure I've seen this somewhere else.
