I really enjoyed the mix between planning ahead and having to take quick decisions in the heat of the moment. Great soundtrack as well, really embraced that retro feeling of C&C back in the day. Very nicely done!!

Nice! Well done on the effects, the feel was solid. Overall great job!

Two minor bits of feedback:

I played the game twice, once without reading the instructions and once with - I felt it actually didn't need as much explanation as was offered. The only thing I missed was the drag-to-aim.

Since the goal was to save as many evacuees as possible, it didn't seem that interesting of a decision to power down the rocket. Maybe it'd be cool to have to decide between turrets and shields instead?

Nice Idea, I wish to see more level with this idea.

C&C inspired simple and effective controls, I'll probably make smaller the base and bigger the towers to give them more importance, I'll probably make all the arts from the same perspective probably top-down, overall fun to play and it's all that matters! :D 
well done!
