Loved the message but after getting the four main GEMS I felt I was stuck.
Is there supposed to be a "Arrived @ Utopia" message?
Glad you liked it! The background colour should change when you've transformed all the basic elements and all parts of the city.
I'm not sure what I'm missing, I've clicked everything but nothing else in the city seems to need changing. Doesn't seem like I finished the game though, the gems turn back into grey blocks after some time.
