The developers don't care about what I'm about to say, if they did they would have fixed it based on all of the many other reviews that state the same thing. U get 30 energy an hour. The things u need the most to make progress are anywhere between 40 & 250+ (the low energy stuff is a waste of time). To complete a task u may need up to 10, 15, 20+ of an item that cost high energy to collect. If u don't pay to play (I did and regret it) u will make VERY LITTLE progress. DONT WASTE YOUR TIME/$$.
