+ Really like the artwork
+ Simple to play
+ Like the skip time option
+ The fact that it keeps playing while offline is awesome!
- I would really have liked some gentle background music
- It would be really nice if there was a little more animation in the world - trucks moving between factories or something similar. Apart from the smoky chimneys the world feels a little lifeless
- I would prefer to have to build the resource factories too - I really didn't need metal or glass for a really long time!
