Pretty Sweet
For the most part, the controls are simple and work very fluidly. The music is fine and the graphics alright, lag is minimal. Gameplay as a whole is great, as is the energy drinks.
However, being a one-hit wonder is not that much fun. I would suggest that whenever one hits a spike/saw/etc... they lose a certain amount of energy, instead of instant death. This allows for one to continue after racking up quite a length.
That's the only real qualm I have with the game. Apart from that, it's great.
