Castle Crush is the thirtieth level of Donkey Kong Country 2: Diddy's Kong Quest and the twenty ninth level in the Game Boy Advance remake for Donkey Kong Country 2: Diddy's Kong Quest. It is the third level of the world K. Rool's Keep and the second in the remake. This level, along with Haunted Hall had a replacement level in Donkey Kong Land 2. Reasons being that the Game Boy's limits were going high during development including the memory and graphics. Instead, these two levels were replaced with Dungeon Danger and Krazy Koaster respectively.
