Things I wanted to put into my game:
The ability to purchase new turret types in between levels to either upgrade or replace ones that were destroyed.
More variety in asteroid sized and looks.
A final boss of some type, possibly an alien space craft which can only be damaged by a special turret type.
I spent nearly half of LD just trying to figure out how to turn this theme into a working game. It was not easy.
Hopefully next time the Theme is one I can just dive right into. All in all it was fun.
Till next time!
