Taking 7 shots on level 28 should score at least as good as the 8 required, especialy as 7 is the obvious number and I found I had to shoot a wall to get max score.
To unfreze after using features just click on the notdoppler button and close that winow/tab and then return to the game, the walkthrough button works as well.
The only problem with the locked content is that all the high scores belong to those who CHEAT!.
if a seperate set of high scores existed for the rest of us there would be no problem, as all trophies and achievements are obtainable without the use of kreds.
All trophies earned without any bought in items,

Acheived a distance of 1,203,164 and a height of just short of 65,000 in the same turn as I aquired level 20. WHO NEEDS KREDS!
