Unfinished Games: SNSD

My first real attempt at a side scrolling shooter in flash. Started earlier on this year, was going good until I hit a wall, ironically, on hit detection.
as of this build 3 of the 4 attacks work: sword attack deals medium damage at close range. kunai shoots long range with low damage. and bombs can one shot most enemies. There are just 2 enemy types right now, the weak fast guys and the brutes. the item shop is open, there you can buy kunai, bombs, seals and extra lives(both lives and seals are currently useless)

again, not much of a game right now. but if you have constructive criticism or programming advice i'd love to hear it ^_^
