Best scores

Are there any secret ways to score points that lead you to a best score? I have looked at a bunch of levels where I have completely cleared all objects, (without letting the enemies destroy any themselves), and if I look at the damage score and add in perfect scores for everything else (i.e. 2500 round, 2500 blood, 1000*rate, 2000*enemy dragons) I still would not have hit the best score.

Some skills score higher for breaking blocks then others.

I've seen 23983471329847982471 score (or something like that)
Now that's glitches Angelo score... They fixed Angelo glitch but not the score so it's unbeatable now

there was a glitch score in server 5. ALL scores from 4-1 to 4-45 have like 300 mil score. now its cleared.

and yes, i found out that grenade gets more scores than ice cube and ice rain etc.

Yes, it's fixed

I am just using my Roco for now as he is level 31 and the others are all level 20 or below. There are a few levels (like 1-15 for example), where I am 4000-5000 points below the max. There are only a few blocks lying on the ground when I am done, I get the full 2500 for the rounds, full 2500 for blood, 2000 for the two star coins, and kill all three dragons for another 6000, so all that is left is damage. But 4000-5000 damage for three or four brick blocks? I don't think so.

I hope this isn't what is causing me to fail to get map piece 4 from 1-15 or I will be really mad.
