This game is too dull, you really need to add more features to this game to spice up the experience. Like power-ups (Mirrored/random saw-blades), hazards (Danger-fields), varying game-modes (Arcade/Objective modes).
As for the visual style, it's fairly decent, an animated/changing background would be nice. Though this just feels like a Fruit Ninja clone without the charm, so you should work on the some game-play/design alterations to help give your game some identity.
Overall, the core concept is solid, but overall the game is lack-luster and serves as little more than a time-waster.
