Once you start to figure it out it is really cool! Really liked it, can see the awesome potential. Getting some pathfinding on the ships. Probably was hard making the enemies stand apart with the limitations of only 2 colors.
Glad you like the game! Indeed, the ships need some pathfinding added to them. Currently, they go to the center of the map and attack everything in their path. Knowing this, you can easily setup your base and build an army without getting attacked.
