Really fun, here is my humble feedback,
The game crashes after a while and the save does not work. Also it is really nagging me that the base is not aligned to the grid and that it is not center. The zoom out could be larger/ the map could be bigger. The tech tree / research hub needs visual design work to be more understandable. And a minimal toturial would go a long way.
But it is really cool and you should develop it further.
