I like this a lot for a one-man indie effort. Like a previous poster said, this is actually impressive. I even like the art look a lot, even though I imagine all a lot of modern gamers see is an "old look", it is a very good look for this old looking style.
Stick with the Warcraft II level of simplicity, they don't make games like this anymore (not this simple) and people like simplicity. Don't start trying to add a lot of features found in modern RTS games, stick with the "old school" design theme. Both because you are a one-man show making an indie game AND because this appears to be on its way to becoming a great nostalgic RTS experience for a very large audience of people out there who haven't played a game like this in a long time now.
Minimalism can be a plus, when done well, and this is looking very good from that perspective. One of the best games ever made was Avalon Hill's Acquire, and there is very little too that game. Personally, I like what you are doing here a lot and this looks like a game I would enjoy playing. You might look at Stardrive 2, it's a minimalist Master of Orion game that I like playing occasionally for the very reason that it is just the heart and soul of what that type of game is without all of the modern bells and whistles added on too it as if they are a checklist that all games like it must have.
I see your game as a the Stardrive 2 of Warcraft-like games... which is a good thing in my book!
