Signpost

## Description

_Signpost_ is a puzzle game where the player needs to enter a sequence of
consecutive numbers (1, 2, 3…) into the squares of a grid. The player clicks
and drags the mouse between two squares that follow each other in the
sequence. The first and the last square of the sequence are indicated from the
start, and an arrow in each square shows the direction in which the next
number in the sequence should be located, but the exact location of the next
number is up to the player to determine.
