An ok Space shooter, I did like that you shot automatically, and held a button not to shoot. That made things much easier. The visuals are very good to the point of being professional. The music is a little repetitive, but what really kills it is that it's actually kinda boring. The levels scroll by far too slowly, and after just one or two upgrades to the gun I was killing nearly all the enemies even before they came on screen, and each level being almost ten minutes long didn't really help.
I noticed there was a rating system at the end of the levels, and I got A's on all the levels except the scrapyard, but not knowing what that grade is based on, there was no incentive for me to go back and play through the whole level again.
As a side kicker, I went through and beat the game, but at the end of New Shanghai the game glitched on me. I killed the boss, and the dialogue went through, but then I was just stuck on that screen and had to press J to get out. at which point it was an automatic mission fail.
The idea of the sentinel side kick was nice, but not very helpful. He could take damage for you, but the way he followed you around didn't really allow for a very strategic or tactical way of using him as a shield. I'm sure his extra bullets were helpful, but once I was upgraded, and my shots filled nearly the entire screen I was more just kept confusing him with a baddie than him actually being helpful.
As for the clicking abilities, that was a nice touch, though again, I found only the original one to be useful. Most of the enemies were dead before making them unable to shoot was helpful, and I was maneuverable enough (and didn't want to drag the long levels on any further) That I didn't need the "Super speed" upgrade. The magnet was nice, and the shield was nice, however, again, I was maneuverable that it was the most beneficial to be able to kill enemies on the other side of the screen as well as those behind me, and it wasn't too shabby with the bosses either.
Finally, I never upgraded to a different fighter because the added damage and energy regeneration wasn't worth the loss in speed, added to the fact that the ships were just superbly expensive, and there was no way I was doing any grinding (through the long long levels) to get them when I was already kicking ass as it was.
So good, but not great. a nice time waster if nothing more.
