i've made it to 86, several 81,82 84 but never to 90, any ideas on how to help them? seemed as the game progressed so did their deaths, 60's then to 70's then to 80's and then it dropped down to 70's and i can't get them back up. i usually ease up on them once the puzzels are solved and just let them coast along, not even trying for EE's, but then they started dying earlier? is this just coincidense? anyone know?
