Here we have 30 levels that I can play time and time again without getting bored of any them. I hope you enjoy :) (they're not in any particular order)
A few honorable mentions:
Happiness valley - My all time most favorite level (sooo should have won the contest) Corners challenge - like the best Pof level ever, which is saying something as they're all amazing Chaotic Rift - Pretty sure no explanation is needed here... Hanging Gardens - Pure beauty. Plus I have an awesome highscore no one will ever beat ;) Cave adventure - this was the last level i beat before finishing all the levels the first time. A couple of months after, a checkpoint was added. Great. The Power of Skill - The level made after I completed all the levels. I want to personally thank pineappledude for helping me procrastinate from school work for six months :) Shivering Isles - I love this level soo much! Evolution fall - Thought I'd mention this just for the sheer volume of background packed into a small area. Plus it's in a world where jagged green rocks seem to be growing berries.
and all the others too, I just can't be bothered to write 30 things about levels right now :P
And of course it makes me happy to see that two of my levels made it into the pack as well, thank you! :)
