The aim of the game is to slice the paper down in size (fruit ninja style) until 10% or less of it is left. The trick is that you cannot slice off a piece that contains an enemy (if you do, you lose!). If you're having trouble, use P to freeze the enemies. When you get down to 10% you proceed to the next level. How far can you go? Respond via comments.
This version has more lives than griffpatch's version — and you get to slice the paper up more! However, the levels are now much harder, with more enemies that get faster every level. I will be surprised if anyone beats level 12. I almost beat level 8, but lost at 11%. I also added a slightly different color scheme.
