A decent short game.
Slightly annoying things:
1) Clicking off the screen will pause it, but after clicking back on the screen (on the side away from the blades) the hand won't always move back quickly
2) clicking the trophy icon when it pops up activates the trophy page, but doesn't pause the game, so when you click to exit the trophy page, the game instantly continues with the hand where your cursor is (under a blade)
