Something I read on the Dexterity forums was that Mike Boeh of Retro64 found out that the easier you make the demo, the better sales will be. Therefore putting a challenging level in there may not have the desired effect sales-wise.
The new level you have put in, is one of the ones I really struggled with in the main game - and I would consider myself an experienced player. I would consider fading the level out once the first ball has been hit, and say to the user 'please buy the full version to play the rest of the level'. Otherwise I can see too many people being frustrated by that level.
Also, I found it odd that you show the buy button while you are playing even though you can't select it.
