Sorry in advance, I'm about to toss a ball of criticism and my games really aren't that much better, so take this with a grain of salt :) 

While I may have liked the music and art of this game, the  instructions were hard to grasp, there is a distinct lack of feedback in the players actions, and the UI is tedious.

I find that it is really hard to understand what each action does and why you would do something at any given time, which is really important for a strategy/tycoon game like this. I think this is, in part, due to the convoluted and confusing instructions given to the player. You should find a way to ease the player in better or find another way to explain the rules of the game.

In regards to the UI, it's certainly functional but it feels annoying to use and has a distinct lack of satisfaction behind it. Maybe try giving the player dedicated buttons to certain number amounts instead of typing it in every time? Also, you should skin the UI to look like the rest of the game, it's actually pretty easy with Unity and would make it look a lot better!

Now, with all this it may look like I don't like the game, but I actually enjoyed playing it to a certain degree. It may have been confusing but the music and graphics both lend themselves to the tone the game is trying to convey.

Pretty good, and very good music! Congratulations :)
