The game doesn't have that much of a fun gameplay.

Everything great except...too easy.You could basically pass through defenses and win.Also,it need saving game function.Above all, everything is great!

Great graphics, sound, and controls...poor playability.

Should have a save game function so I can try again....gets annoying when you have to start over every time.

Good Game. I liked how the game play was set up overall. However, the amount of money you get from destroying enemy units is kinda low considering the price of upgrades. I would also suggest that the plane have free movement across the screen instead of being fixed at the bottom middle of it. This will allow greater movement, making it easier to dodge enemy fire and target enemy defenses.
