Hey, I tested your game :)
What I liked:
The idea that I have to optimize my resource intake and make a perfect balance was really fun.
The tech tree, and that there was different types of resources. At first the constant sending of unit immediately was a bit confusing.. but in the end, I liked it. It was simply a new concept I had to get used to.
What I would improve/change
The uncapped resource deposits, that I could just spam as many harvesters as I wanted, makes no sense, and that there is an unlimited amount of resources, also made no sense, this means that I never need to exapand my colony
The tutorial was insanely slow, and that I had to wait for the voiceover to finish was just not a good experience.
I would create a better and more controlled progression in the game itself, so that a tutorial was not needed.
