The controls are flakey, the instructions are vague, the boundaries are very weird, the starting point can instakill you, and the game is a little too challenging (possibly because of a combination of the above). That being said, I see a lot of potential for this if it is polished up a bit more. 3/5 pending the next relase :-)
An interesting game, however the controls are quite obnoxious. It feels as if the way the game is controlled detracts from the experience instead of adding to it.
The pause menu needs a "restart game" option... getting to level 30 on 1 life then having to either a) wait to die or b) refresh the entire page... wel, sucks
