My thoughts so far.

Thanks for the feedback! I will try to improve it with time and add some new items.

Some notes:

[*] The ships clip into each other due to the drawing order of sprites. I did not have time to create my own drawing order for the game engine, so when the ships are pieced together from many pieces, and the turrets are on their own layer, they clip when they are on top of each other.
[*] Units firing when exploding is up for interpretation. I think even in this real world a big naval ship carrier or such can keep shooting even if it's about to explode to pieces.
[*] "Harvester" - units can harvest resources from nearby exploding ships. I think this is what you mean with the station that costs a lot but seems to be weaker. Granted I could have tried to get a better explanation somewhere but I only have it in the help menu now.
[*] I have added BSE Marineclone to make replenishing marines possible.

Thanks again for the feedback!
