Just Plain Awesom
At a glance it seems to be just a side-scrolling shooter, but seconds late you see that it is more than just that.
All the enemies you 'kill' actually can become part of your airship, thier guns become yours, and they become clumped together with your ship to create something that looks like something Hayao Miyazaki (Howl's Moving Castle) would think up of.
And when you are not doing that, you can create your own ships to play in the game, as well as the weapons and stages.
Trust me when I say, this is not just some tacked on editor, where you can only work arround a basic design. No no no, I was able to create Boba Fett's Slave1 from scratch.
And the weapons are just wonderful, you can have your custom ship firing rapid fire, lasers that zig-zag, rings, clusters... I really can do this game justice with my decriptions, you really just need to see it for yourself. And another thing, whatever you make, you can send to a fiend.
Really, stop reading this, and go pick the game up, at only 40 bucks, its a great buy.
