Sorry for the slow reply, I had to much work, and it took me a while to get to testing.
However, here is my playtest of your game :)
What I liked:- 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.
- The idea that I have to optimize my resource intake and make a perfect balance was really fun.
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.
I would create a better and more controlled progression in the game itself, so that a tutorial was not needed.
The tutorial was insanely slow, and that I had to wait for the voiceover to finish was just not a good experience.
