## Description
_Lattice_ is a high-speed abstract rail-shooter. The player constantly moves
forward at a rapid pace along straight square pathways connected by junctions.
Enemies and obstacles swarm from all sides, attacking or obstructing the
player, which must either shoot and destroy them or avoid them by either
moving to other sides of the path or jumping over them. The player can change
their path through the stage at various junctions, as well as turn around and
head the opposite direction if necessary.
The goal of each stage is to locate and capture three “key capsules” within
the time limit and without running out of life. As the stages progress, they
become increasingly complex, introducing more branching paths and ways to
traverse the paths such as the ability to jump to adjacent pathways. There are
also a variety of special weapons that can be found.
At the end of each stage, the player is graded on several criteria and given a
score. Progress is saved using passwords. There are three difficulty levels,
and seven stages in total.
