I just realized, that after you beat the final boss, your friend is just dropped, if you can how do you save the friend (i also noticed on that levels page you can see a stickman jewel, like the puzzle piece and color buddy and heart).
If you collect all the puzzle pieces in every level and play the final level again, you'll notice the puzzle pieces have come together to form a protective barrier so your friend doesn't fall to his doom!
Thanks! However getting all of them will be though, i may wait until there are guide on youtube.
