Love the game but a few things I would like to suggest
1) Allow road to be able to build over the lava. This allow us to access resource on isles that's too small to be useful.
2) on sector A9 a bit fewer avenue that the bug will attack from would be nice so I can actually access most mines and not be stuck on the bottom left corner
3) have a single-player skirmish mode where play can choose map, and such against the AI would be nice.
Those are all the things I have so far. All in all pretty good game so far. Fairly well balanced and well designed levels other than sector A9 with the lack of sustainable resource mines
