Not a bad game, but the stress system is messed up. I had difficulty with the game until I learned NOT to upgrade your buildings except for the resting ones. You gain stats faster that way, and your skills increase just as fast because every upgrade makes you more stressed out to study. That's just dumb. Still, I enjoyed the game. 4/5.
Good game. My only real problem was the 999 energy cap. It's ridiculously low--especially because I was getting so much more than that at the end of the game. Yes, it's true, the units use electricity when they recharge skipping the energy cap for a second, and so you can cheat slightly, but, really, it is just frustrating without giving any benefits.
