Strange.
I went through the same levels (1st beat) just about week or two and now I usually die at 87-88. Well, I still lost 1 life every 1-2 level in 80s, but I don't think 84-85 much harder than others.
I beat 84 this way: (numbering is as in cadomax)
make pear #5 fall, then kill #2 by throwing green bombs through teleport. Wait until #3 turns left, jump to it and bomb it. Wait until #1 turns left and bomb it carefully. Then a bit harder: go right and do freezing #1 through teleport until you see that #4 and #5's bombs cannot hurt you, freeze #4 and take blue bomb. Bomb #4, #5 and then #1 fast, get golden igor and kill all from upper teleport.
Ehm. Annoying level, i agree

85 is easier, I think. Look when it's safe to jump down, get blue bombs, and repeat. Then get down all others.
Sorry for my not so good English (I forget it because it's nobody to speak with

4 years...
Well.. good luck
