Here is our 3 star walkthrough video strategy for Amazing Alex level 4-17 The Treehouse, also called “Alien Escape”. Your goal is to get the paper airplane through the trap door and through the hole in the floor below. Note that the paperclip tip and the ball bearing are both attracted to the magnet, so position these wisely.
If you have a different strategy for completing this level feel free to leave a comment below.
put the buzzer and bouncy ball where the video has it, put a pinball right behind the plane point a magnet at the pinball pushing the plane, put a diaginal plank leading into the hole when the plane hits it, good luck!
