This may sound weird...
But whenever I try playing, I can't seem to get it to start. It just flashes the title and some image in the background.
Update your flash player.
A few things you could do to improve this would be to add a boss to every other stage or so, and maybe fix that one bug...
You know, the bug where after you kill a ship, there's an invisible barrier around where it exploded for half of or a full second. Kinda makes it hard to kill the others.
All in all, great game.
Just one thing though... I half expected that Sonic version, where Tails, Knuckles, and Sonic do the same thing. But meh, loved it. Specially the one mixed with that SLAM song.
