I agree with everything that Tsun said, but I would also like to add that that enemies spawned pretty much right on top of me far too often, to the point that I often felt like my death wasn't my own fault.
That being said, I really like the idea that body length = score multiplier, since a longer body means more points but more difficult navigation, an effective risk-versus-reward scenario.
Unfortunately, I felt the gameplay and graphics to be lackluster. But for your first game, I think it has a lot of potential.
