I enjoyed this simple game, it reminds me a lot of fishy and other such games where you eat other fish to grow, but in this one you added a unique spin where you have to grab an item and stay in place to score with it, but it gets harder and harder to stay where you need to. I managed to get a score of 90 before I was overwhelmed (it required every cup of Joe I saw). I like how you also used the colors to differentiate the sharks' speeds, with yellow being significantly faster. To improve on what you already have here, I would say to put the pickups on the top layer because as there get to be too many sharks, you can't see them underneath and it's harder to get around to them then because it's harder to keep track of where they are and not take damage at the same time. It would be a good idea to add some other powerups too, like an autoscan that will automatically scan the papers you pick up for a limited amount of time even when you are nowhere near the fax machine, invincibility, bundles of paper that just pick up more than one at once, and a super bomb that wipes all enemies off the screen for a time. The changes that heinz23 suggested would also make for a better experience. All in all, it was a unique and original idea, but it could have used a wee bit more.
