A good game, nice idea and I really like the touch of instrumentals. Several points that my fellow players may suggest: First, Instead of 70 enemies all having 1 for speed and 10 for damage, maybe it be better if there was a change in the random settings? Also a variation of enemies with different attributes would definitely bring about more colour to the game - keeping it spontaneous. Have you also considered the idea of different levels or upgrades to the blue sphere as the player progresses?
Good concept and nice game, I hope these ideas may be of some use to you :D

The concept works, but it would be an idea to put in a reaction time statistic as well. (time they enter the camera's field of view-being shot/number of enemies) and base it off that because when you're waiting ten minutes for one to come along and manage to hit it you're gonna have an acuracy of 100% :P
Enlightening though!

It starts out way, way too slowly. The game should remember when you demonstrate that you're not a noob, to start off faster than 1 enemy every 10 seconds that you can kill with a single shot.

A novel concept, but the reactive aspect is rather slow, i.e. the "flow" adjust at such a slow rate that the standard gamer will likely not reach the full potential of the game before the timer runs out.
