Mario vs Donkey Kong

In here, there is a wall of red blocks that keep us away from the Key. Lets get passed this barrier by jumping off the trampoline, climbing the chains and drop down. Jump on top of the Key and perform a backflip to collect the Red Prize without hitting the Blue Switch. Next grab the Key and hit the Blue Switch, the red blocks will disappear. Throw the Key on to the conveyor, hit the Red Switch, jump on to the red platform and backflip on to the top platform. Go left and grab the Key. From here jump on to the trampoline and land on the platform. Put the Key in the door and part one is now complete.
