Having played this series from the start, one thing I think would make this better is if there was more story - and involvement - in each map. As it is, it's almost like reading a book that consists of chapters that are only one page long. And this map was way too short - only 4 emitters which never posed much of a threat at all.
So for the story aspect of things: Think of it kinda like a research paper, but a FUN one. You have an introduction, a few points, then a conclusion... In this planet, there was essentially just an introduction.
1 - (Intro) "We've landed on planet ____. Here are a few miscellaneous details about the planet _____. Our situation is ____ because ______
2 - Our primary objective(s) should be to _____ because _____.
3 - (Conclusion) "Yay! We didn't die and we actually defeated the enemy. Now we need to ______"
You actually did this in a few of your previous maps - which is good for the storyline. Maybe put a little more stuff (storyline and enemies) in each map if ya can.
I do appreciate your work that you've put into these maps - I'm giving this feedback hoping you'll continue to make them and continue to grow your map-making skills!
Thanks again for making the maps!
