Wow. Simply astonishingly fantastic gameplay.
I love this game.
Especially the secret upgrade that turns your airplane into like the hedgehog from hedgehog launch, and other things as well! It's one of the best horizontal flight games I've ever played, like those ones where you have to get further collect powerups after being thrown, such as toss the turtle and hedgehog launch. This outlasts them by far!
Although it's not a shooter...
