Thank you for participating in this round! We hope you found the problems interesting and/or funny.

Special thanks to dorijanlendvaj for helping with Polygon related issues. Preparing good tests for certain problems was in fact a good problem in itself (in fact, sometimes they were hard enough for usual CF rounds), and we will mention these problems for the interested reader.
