Boundary value analysis is important because it focuses on testing the values at the edges of the input domain. In the context of a maze game level, this means testing the conditions at the limits of what is considered valid or expected. For example, the maze might have a minimum and maximum number of items to collect, or the player might be able to move only a certain number of steps. Testing these boundaries helps identify errors that might occur when the input is at the limits of the expected range. These errors often arise due to off-by-one errors or incorrect handling of extreme values.

Example of a boundary value test case: Suppose the level is designed to have between 5 and 10 items to collect. A boundary value test case would be to test with 4 items (the lower boundary) and 11 items (the upper boundary). This helps ensure the game logic correctly handles the minimum and maximum number of items.
