Clear Open Paths First
Level: Basic
Remove arrows that can already escape to open up space.
The safest move is always to clear an arrow whose path is already open. Removing an arrow empties its cell, which can open up new paths for other arrows.
Removal never blocks another arrow's path. So as you keep clearing open ones, new paths naturally appear. Handling the sure moves first is the basis of a mistake-free run.
