I get a new task to pump the water - 2 stars. As soon as I get 2 stars the pump is broken and I need 2 stars to phone Colin to fix it and that needs 2 stars. Get those, phone Colin, need another 2 stars to fix pump. Do that, now need 2 x 3 stars to pump the water! No doubt there will some other problem, subtask before I finally finish this one task!

Come on developers, make the meaningless sub-tasks 1 star at least - like making a phone call. Or make it much easier to get stars. I don't mind playing a level a few times before finally winning but getting stuck on one level for days and having to wait for my 5 lives to refill isn't fun. I scream in frustration every time I think I've got enough stars to complete a task, only to find there's another one ... Grrrrrr
