The goal is to transform the entire playing field into your territory while removing any enemy influence from it. To do this you build constructions that spread your influence or attack the enemy territory. These constructions cost resources which you build up by moving in synchronization with the beat.
You move over the playing field with the W-A-S-D keys or the arrow keys. As the tiles are hexagons, moving to the right or left will not result in a completely horizontal line, but you will stay within the "lane" of hexagons. With the spacebar you can construct buildings if conditions are met. See section Buildings for details.
In the lower part of the screen you have a simple GUI to help
you get an overview of the beat, the resources and the overall
situation.
The long line with the moving bars on it represents a moving timeline
of the beat. A beat happens just as a line passes the center of
the circle, which itself briefly flashes when this happens.
The light purple bar on the lower left denotes your synchronization
level. If you move with the beat it goes up; if you don't it goes
down with every movement off-beat.
The white line in the bar is the building cost. If the bar reaches it,
you can construct or upgrade a building.
In the lower right there is a bar that shows the overall influence on
the playing field. The further into the green part the bar is, the
more influence you have.
Each faction starts with three starting buildings in the corners. You
cannot construct or upgrade these, but they will help you establish
influence over a small part of the playing field.
If you are standing on a transformed tile of your factions (it will
have a green outline and look different than the neutral middle) and
have enough synchronization, you can hit the spacebar for
construction/uprading.
An empty tile will turn into a tower, which raises your influence around
the tower and spread it further into neutral territory.
A tower will turn into a power tower, which does the same but spreads
twice as fast.
A power tower will turn into a thrower. Throwers don't generate influence
by themselves, but will attack the enemy territory at random.
The influence on any tile they hit will be raised or lowered to the
benefit of the faction the thrower belongs to.
