Too much for too little
The hero's main power is shabby at best, and the upgrades for it do little to improve it. It would be better if the upgrades gave the power a wider effect instead of having it shoot multiple lasers in different directions.
Overall, there is a lot of stuff happening on the screen, but the game still feels repetitive. There should be some breaks in the action that evolve the story and give the feeling that you are moving towards an actual goal.
Also, it appears that the points after you lose are messed up. You should check that out.
