Sorry to frustrate you with bad controlling and tricky levels orz. 14 is hard both in puzzle and controlling. need to jump and scale at the same time to get to the ladder. then easily jump to the blue box ( scale it to the smallest ). Then again, shrink to get higher and jump and scale at the same time to reach the heart.
the key is to jump and scale the same time. A tricky one ; )
thanks for playing! Hope you enjoy it!
