pretty fun game! nice mechanics and actually got me thinking about how to optimize an idle game! most idlers have you on a linear path where optimizing is obviously only one choice (or there is only one choice). here, you must think about money, research, and land use. each affect the other and the most optimal choice changes throughout the game! only 3 stars instead of 5 because after (maybe 10?) prestiges, the game didnt give me money from my 2 windturbines and now im soft locked. now broken

Fun game. The relentless pressure to spend money takes away from some of that though. I understand the game is free and the developers need to make money but being asked over and over and over is just annoying I mean most people either are going to spend money or they wont. I dont think the constant annoyance of having the offers shoved in your face every 5 minutes is persuading anyone on the fence which is why I think they do more harm than good. Other than that it's a quality game

The app is quite-well thought out, and gameplay is interesting (and addictive). One thing that could be improved is adding tutorials/hints that explain in better detail how the game and its pieces work. Don't know how many times I blew up generators and coal burners before I figured out the generators needed to be upgraded to handle the heat output of the coal burner. That's something that could have been explained better.
