For fun I decompiled the game to get the answers. Suggestion for anyone else who thinks of doing this: don't bother. All the answers have been one-way encrypted.
Woah, I got some kind of weird bug where my shield energy went off the screen. Also given me a ridiculously high score because of the shield bonus. o.O
The lack of saving unless the page is closed properly is a bit annoying, and doesn't happen in other games... maybe you could ask about it on the forums and show your shared object code there to see if there is anything wrong with it anyone can spot?
Well, I just tried this game again and I've rediscovered why it's the only medium badge I haven't got. It's far too hard on every level; basically if you miss a headshot or some suiciders are slightly too spread out for shotgun you're screwed. It doesn't have a way of resetting the level other than waiting to lose or reloading the page. Sometimes you complete a level and it just freezes, forcing you to reload the page, at which point you lose your progress. It runs extremely slowly for no obvious reason, making aiming extremely difficult. And additionally, it has another bug where any ammo you buy is lost if you reload the game. WTF.
