I am so sorry but I have to say my honest feedback! I know you had a cool idea of time management and how to choice etc... But you made some Big mistakes that made me close the game and not continue playing...
Very poor and bad way to explain how to play! the screenshot is full with things its like a rocket science blueprint.
Not very interesting visual feedback
The game is design to make u feel its a framework for tower defense game, just a proven mechanic.
These were my feeling/experience when I played it, but I'm sure you idea have potential if it was represented in a different visual style
Hope my notes help you improve it, Good Luck.
