Great game, but $8 to continue?!?!

This one is as good as the others, but when Ive finished all the basic levels, they charge $1.99 to go to the end, with no ads.
$8-?!?!- I usually complete the free levels in an hour or less, and wrap it all up an hour later.

Put $1.99 or less (some are just 99 cents) to let me play to the end. $8 is WAY too much! Thanks
