Tower block game
fixes #629

1. Start the game either by pressing the Spacebar or by a mouse click.
2. Now either by using Spacebar or mouse or even your finger try to stack the blocks as high as possible with utmost precision.
3. Each time you perform step 2 you get a point. If you fail to do so, no problem! use any three navigating methods to restart the game.
