I love the idea of this simple micromanagement game. It has elements that I love - monitoring the systems to make sure everything is stable.

However, when changing value on the machine, it's never clear whether I need to be increasing or decreasing values. It eventually got rather annoying to hear the beeping noises going off constantly as well, especially when the danger was not so apparent. Maybe only have the sirens blaring/flashing red lights when multiple things are at critical levels.
