Level design only has minor changes consisting of reducing the amount of moving platforms. Instead of a life bar, you have a time limit! Start with 1 minute. Maximum of 65 seconds HP ups now give 10 seconds to the timer. Damaging a boss, using a box to press a switch, or defeating an elite foe gets 7 seconds. Getting a key, hitting a normal foe, or clearing a level gets 5 seconds. Clearing a level gets 1 second for each level completed Dying removes 1 second.
