Greedy dev. Changed from 4 star to 2. Played like 2 years ago, threw some money at it, pretty enjoyable game. This time around I'm not buying any upgrades and WOW this game is very demanding. Between the constant optional ads that you dismiss and pop back up within the next minute or two, you'll eventually be hit by the sneaky "wait until you're invested then pay to progress" move. At one point you'll have to delete eeeverything, replace them with research centres and wait for 2 days. REALLY!?

Its fun as much as these types of games are. Standard grind but it has me coming back. However the tree/rock is just a money making scheme that leaves a bad taste. 4 axes/tnt to remove one. Wait an hour for each to regen or watch adverts. So 4 ads per one, 30 seconds each... Its slow and frustrating and ruins the game play. 1 ad at a stretch 2? More is just greedy. Sure I can buy £1.79 for 50 of each. To clear the first and second lands would costs too much. Other than that its a fun game

The game can be a fun little time waster, but the pricing for things are way too unbalanced. At one point I had 1 power plant and 6 islands full of the best banks I researched to sell the power, and I still couldn't sell all the power this 1 power plant was making. And the batteries to store excess power are next to useless, don't bother with them.
