Hi, I've made a video about the game and wanted to share some feedback about it :D hopefully it is useful to you :)
-The main concept is pretty good and there are some ideas like the "investigation tree" that with some extra work on polishing them could be awesome.-The gameplay mechanics you have chosen work quite great and by expanding them with extra resources, new technologies to investigate, etc. you could end up with a very solid gameplay experience :)
-You need to make a tutorial ingame or at least polish the first minutes of gameplay because as you can see on the video a new player could get easily blocked by the game at the begining making it restart the map.
-Visually the game doesn't look bad , but I think that with some extra work on the lighting of the map and adding some extra particles to certain actions could make the game look even better that it actually does.
In conclusion, the idea is great and I hope you keep working on it. Hopefully this is useful for the development :D, also if you could subscribe that would help me a lot :)
Regards
