Cloudberry Kingdom

The Level you have to beat for this, is 160 in adventure mode. After the Cutscene is finished, the Achievement pops up. If you need help in the later stages and i am sure you will, you can buy the slow motion and the ball who guides you through the level. But later they become more expensive, and so here is my hint:

If you are running out of gems, just play world 1, collect all gems and then return to your current level. After a few trys and with slow motion and the guide its possible.
" If you collect all gems in one level you get 10 extra, so try to get them all ;) "
