How to play
Mission: Collect all the objectives and turn back at the base with the minimum count of steps.
How the game works:
The pawn can only move in perpendicular directions, not in oblique ones.
When the pawn is on a boost, it triggers all the gray boxes in crossable space (equivalent of white boxes) for 10 steps (1 step means 1 box changed).
While the pawn is in a gray box and his boosted tenth step is triggered, the pawn is immune and is able to move.
