I have realized I have no problem keeping up with pace later in levels, and so I am lowering the requirement for double hammers to scores I get that are less than 100,000 point after level 4. Unfortunately I am in a slump as of late. It's a combo of running into bad luck, or just finding the craziest ways to die. Like not knowing that if a fireball is about to go down the ladder that if you go up on top it cancels out the fireballs path down the ladder. That time the fireball reverted to going after me, and killing me quickly.
