The Ranks system we have added to Box Maze Extreme is a very simple and straight forward way of rewarding you for finishing the game with as few deaths as possible. You will be rewarded with a special Steam Achievement based on what rank you finish the game on. We would love to hear some feedback from the community in regards as to how we can improve the ranking system as well as to find a good balance for each rank.
