A simple concept, yet a gratifying challenge to master. Played this game for hours as it changes the scenery from jungle to caves to manage health and rescue everyone (it may happen that you can leave someone behind when reaching the level's minimun rescues... always thought about them, never to leave anyone behind). Sadly, I wasn't unable to finish the game, as I always wanted to star all over again, so... I trully hope GOG manages to give fans a new opportunity to fly near impossible rescues for the faint of heart.
