Good solid gameplay - had a real 'Robotron' feel to it - wish I had twin sticks to play it! The music had a nice cyber punky feel, the mechanic of 'last resort' was both a good 'punishment' rewarding staying alive vs dying for the score. Like Serial said - the additions of powerups or weapons could make this a solid game. The one thing it lacked was a 'cooldown' period so the player could regroup - it was constant pressure ramped up arcade style until the player loses.
