EDIT: THERE IS A NEW VERSION OF THIS GAME made in collaboration with the legendary Weebl:

Please check that one out - it's much more polished than this one! Feel free to play this game if you want to see the development over time though...
This game is unlike a conventional scrolling shoot 'em up - instead of controlling the lone starfighter, you must marshall your forces and defend your base!
SDF features intense soundtrack, hardcore blasting action, and sound effects by human beatbox legend Spy Eyes!
You fire your fixed weapon as the screen scrolls by clicking on them. You can also launch fighter wings and use EMPs!
