it's the "tron motorcycle race" concept, you should work on a second version of this: it may improve a bit. i would find easier a "wasd" type of control instead of a "turn right/turn left" command: now you must "put yourself" in the prospective of the dot (i don't know the proper english term for wthis). moreover: the game should resize with the size of the display of the mobile device.
not that challenging... but music, interface, graphic, text, sound fx and the gameplay itself are all a smart, funny and well done parody of a communist race; and, believe or not, this makes it very enterteining and worth palying untill the end. 4 stars.
the game may no the best of all time (nice try) and the gameplay is pretty basic, but i appreciate very much the effort to include the most understimate tool regarding the mobile games: the accellerometer.
the delayed shot weapon is the most powerful one. one complain: i have spent too much time destroying asteroids just to get cash. to get all the upgrades was too boring.
