Great little game, had fun. Thanks.
Nice shooting game with very good graphics. It somehow felt a bit different than most such shooters, in that I had to fly around avoiding bullets while freely aiming at any direction. Controlled auto-fire (on/off) was nice. But as others mentioned, there isn't much else to it... No new weapons (just wider spread), no bonuses, levels end as if out of nowhere. It feels like it has the potential to be much better.
You really need to implement an aiming reticule.
Not bad. The music is really annoying...and yet, the menu music is extremely catchy. I upgraded all my choppers to max by the end, but sort of like the others have said, it doesn't feel rewarding. You just sort of get a YOU'RE WINNER-type screen.
That said, it's good to kill a few minutes.
Smooth gameplay, nice graphics and sound, but it feels a bit wasted. There's no level design to speak of - levels end in mid-wave! - and the game as a whole lacks structure. No plot, no sense of progression/development (beyond a certain point you just seem to get the same types of enemies), no purpose to playing the game once all the upgrades are don... seems a bit of a waste given the effort that went into sorting out the gameplay element.
Pros: in-game experience is proper old-school vertical shooter action, frantic bullets everywhere...
Cons: ... and then what? Lacks sense of reward, other than a few minutes of nostalgic blasting.
