This game seems really hard, but I think that might just be because it's overwhelming. There's a lot of mechanics/options available, so it's really hard to figure out what might be the best in a given situation when you aren't already familiar with the mechanics.
I think that this game could benefit from a progression system that slowly introduces the various mechanics to the player one at a time rather than all at once.
It could also benefit from being turn-based instead of continuous action. That way, the player has time to think about what to do and consider all of their options.
What you do have seems to be a fairly solid management game though. The mechanics are all there, it's just a matter of finding a way to make the player engage with them without being overwhelmed.
