New levels from the game platforms, mobiles and tablets are becoming most difficult than Windows 10!

Why does all CC level designers make the all levels are mostly difficult for the mobiles, tablets and games platforms (Facebook and King.com) than Windows 10-app???

First the new levels are out for Windows 10-app are not difficult levels. Therefore can Johnny Crush for without using boosters to completed! Second the new levels are out for the mobile and games platforms are very difficult and almost impossible levels for without using boosters. Because for the a lot of players cannot complete a levels for without using the boosters. That’s unfair game! Level designers please stop for make all levels to extremely difficult levels for the mobile and games platforms. Thanks.
