Version 2 of the demo released

Version 2 of the demo includes significantly improved gameplay mechanics (faster framerates and smoother controls), a couple of different levels to the previous demo, the introduction of a pre-fall timer which makes the game slightly easier, a screensaver option added just for fun, and the ability to reply a level or go to the next one from a menu at the end of each level rather than having to go back to the main menu. The issue with alt-tabbing out of the game and back in causing problems should be fixed as long as you don't choose the software renderer from options - it should bye set to Direct 3D by default now. 

Give it a try! :-)

The older demo is still available for comparison if you're curious.
