modify this script so when marios currentHealth = 0, the scene changes to _Scene_DonkeyKong25M2. then if marios currentHealth = 0 in _Scene_DonkeyKong25M2, the scene changes to _Scene_DonkeyKong25M3. then if marios currentHealth = 0 in _Scene_DonkeyKong25M3, the scene changes to _Scene_DonkeyKong25M
