I wish I could get a refund on this but I gave the developer the benefit of the doubt for too long. Requires you play in Ironman mode with no reasonable alternative. Have to immediately head for hidden resources every map. Have to keep researching the improved buildings over again on each map. No room for error or even delay in executing the EXACT sequence the developer has in mind. Developer clearly feels they are competing directly against the player. Hero missions where it is not physically possible to get all the reward points because the map has been altered to make earlier guides invalid by removing required pickups. And no sunlight at all, ever. All maps are very dark, enough to make it hard to see necessary details on the screen.
