Thanks! :) Yeah as with my reply to a comment below, will definitely be looking at re-ordering the levels in future versions based on how many fails made in each one when testing.
I just saw this reply of yours regarding the difficulty, and what a superb way of using real-world data to allow you to re-organise the levels order!
I wouldn't have thought of that, but such a perfect way to analyse difficulty when you think of it :)
