Yes I am building for scirra store.
What I will do is create and upload each station separately. The price range will be anywhere between 5-10 pounds, depending on color variations and animations. I will use spriter for the animation, but also provide them as separate parts if you wish to animate yourself. They will be all HD size so you can scale them down to any size you require.
You can see the progress on my behance portfolio, will upload there soon as I complete coloring.
You can contact me from behance as well, and show me some concepts you have created. I was actually planning to add different kinds of turrets, ships and ufos as well as alien planet maps(top view), so these can be used for both space as well as land games background.
Once all are done, I will combine them into one big bundle providing huge discounts, so you will get them for much less, like my current bundles
