Rough prototype of the day. The graphics are placeholders I found with Google image search. To try this, select a tile from "power", then click on a grid to place some. That's all you can do for now.
I've played many space shooter games, but a thing that bothers me is that the ships never have any kind of internal structure. Your ship tends to be just a scalar value like HP, and when it reaches 0 you die. I want ships to have inner structure. Imagine a space battle. Wouldn't you much prefer to hit your enemy in their warp core to cause a devastating chain reaction that destroys the entire ship?
