Reading Arrows and Paths
Level: Basic
Figure out where each arrow goes, and how far, before you tap.
An arrow only moves off the grid in the direction its tip points. Before tapping, trace that arrow's tip direction all the way to the edge of the grid to see whether any other arrow sits on its path.
If the path is completely clear, that arrow can escape right now. If even one arrow crosses it, it's blocked and you'll only lose a heart. Reading the path is the starting point for every decision.
