Really fun game, thankfully it took my only 2 attempts to get the hard badge, it came down to the wire and I had just over 1000 wood (for the final Stone Circle level to stop the darkness) when my last forest got covered.
Lots of fun and pretty intense for such a simple game
Be careful trying to sell items after quests by leaving them in the 'drag to sell' field. I have had several instances where I lost the item and gained no money from items left there. :(
Got to the 4th or 5th screen, it when moving between levels it didn't scroll far enough for me to actually do anything.
I hit quit to reload the reef, and was happy to learn this completely restarted my progress. Glad to know quit restarts the entire game not just your current reef .... :(
On the achievement screen there is a button called Satellite view at the bottom left. If you click it it shows you where every ATM and hidden place are. As well as the routes to go outside.
Good game it was fun. If you are having trouble on the harder levels just pause the game and do everything, I couldn't beat the last mission on gold leaf until I did that. Once I started pausing the difficulty increase became trivial.
