Mario vs. Donkey Kong 2: March of the Minis Hint - Guideline Tappage
In any of the bosses where you shoot DK with the touch screen, you can press L or R and a line will appear showing where your Mini-Mario will go. This is especially helpful when you have to bounce them off walls and have to avoid hitting other things in the way. Although this line only appears for a few seconds, you can keep tapping the keys as much as you want to show you the guideline.
