I'll try to be nice about this: in the same way one 4-second "game" is pointless... multiple 4-second "games" are pointless. There really isn't enough material here for this to even pass as a game.
Oh, and for the record, I didn't lose any lives ^_^
I am really impressed with this game! One of the most well-made flash games I have ever played. It did get a little old after a while, though - and the third boss is way harder than anything else, which seemed odd. Still, excellent game!
