Awesome!
I really wasn't expecting much.. But this was amazing! You totally got some skill for action script :) by the way, im 12 years old ^^ But well done you surely have some skills i don't have. BUT (yeah.. there's a but...) the game is too short, try making it some longer with some extra difficulty's, like bosses and more enemy's. Also, you can give the round bulb (player ball thingy) some nice weapons and powerups. Just make a neat gun with some plasma thingy and stuff. Anyway VERY nice job making this, i totally enjoyed. Alright.. let me stop typing this review :)
