This game was originally made for Ludum Dare 30 - Connected Worlds.
In lin?ks, you have to activate as many lin?ks as possible. You control space ships on two worlds, and are constantly assaulted by a stream of foes. On top of that, whenever you activate a lin?k, you create/change the connection between both worlds.
Most of the time, killing an enemy on one world will cause something to happen on the other world. But there are two other possible connections.
How many links can you activate with both ships? Can you activate enough to destroy the alien invasion? Will you save earth?
Arrows to move.
X to shoot.
C to switch between ships.
