longest medium difficulty badge ever. i finally got it on level 10 when fighting the boss. of course it didnt update my damage done until the end of level 12.
22 is easy. click the blue blocks on the left and on the right. all 4 of them. then click the 2 red blocks fairly quickly after the rest of the blocks stop moving. should get it with par rating. thats right. leave the blue block in the middle alone.
