Awesome. I overloaded my workers sometimes a little bit. :D I tried to train them so that they would be able to get more energy. The game is not overly tricky. It is a great alpha. I should not expect demo or key competitions to be easy. It was fun, and if I had more ways to progress, I would go farther and get more than 9/10 at some point. I just felt like I finished the game, and it was supposed to the endpoint of this alpha.
ya overloading workers will reduce quality, and ya you basically consumed the current content for now. Right now I am adding more systems into the game but soon I will add more rooms and Large games which are going to come with some added challenges. Eventually AAA which I plan to make you use multiple studios for but still a ways away from that point yet :)
Training endurance will reduce the workload costs.
I am really glad you enjoyed what I have already done I honestly have a lot planned and I hope you check out the new content in the future if you have the time.
