Its a pretty nice shoot em up. The balance of the game seems okay but its very hard. After repeated attempts I never could get past a score of 500. I like how its too hard to just shoot them and that using the shield and hack is essentially required. I also like how there's pressure to kill more enemies as quickly as possible to keep your cpu up; however, it's here where the game's balance is thrown off. Once you run out of cpu you're essentially screwed. Its too hard to fight the enemies head on to recharge since their bullets move too fast thus there's no way to build up enough cpu to get the cycle going again.

One other issue is with the hack and shield abilities: there's no indicator or warning of when the effect will wear off leaving the player vulnerable to an attack as soon as it runs out.

Lastly there is little feeling of progression, sure there is rank ups, but means nothing if nothing additional is gained from it. Giving out the abilities bit by bit might have solved this, but that's just a overall design dilemma.

Anywho, the graphics were nice, good special effects and nice music to go with the action.

Oh yes, the theme! I was going to give you a lower score since I thought you were only going for the "Machine" route with the bad guys supposedly being robots or something which would have been a pretty weak way of meeting the them alone. But! I now realize that the main mechanics of the game is organizing and managing between the different abilities by cycling through them in to gain an advantage. So props on taking on that theme as well!
