Not to bad!
This game although one that has already been done by many other animators is all in all pretty good. Id not say that this game should be properly reviewed because it is missing key things that it doesnt have.
The menu is pretty easy to see but instructions would be better if you used text. Also the same if you created better pictures to go with the "Story".
Including more "things" would make the game overall more fun, more Levels and better quality of Icons in the game. Music something interesting to keep the tension. More sound effects.
Overall interesting idea and game but needs Tweaking.
