Game - Notepad Invaders

Hi, i found a cool flash game today, it's "Notepad Invaders". Just like a classic space invader, in this game we have to kill all aliens before they catch you, and they'll getting faster when they come closer to you, so you have to be hurry. Well you better to try it, it's real fun, i played few times. Beat my high score, i've got 14,050.
