I don't know, why I am writing this, because playing this game is not compulsory... I think that Hell levels are pure agony and designed to be secretly sadistic.
Especially levels, which include pineapple, because sometimes pineapples go havoc and quake at every 3rd second, which makes playing almost impossible, because you have to dodge usually strawberry's ball and sawblades etc. at the same time. Occasionally you get stunned no matter what and refractory period is far too long. At nightmare it is generally speaking one lost live, if a pineapple gets you stunned even once.
54.5 Is very hard because it takes time to kill pineapple, because almost every bomb is threwn away by sawblades.
54.6 is pure insanity, because everybody is shooting or bombing or killing you, because dropping down makes your temporary invinsibility wear of so quickly. If you try to kill enemies through the wall from the upper left corner, it usually takes very long time and makes fireball appear. At videos it works more like at movies and IRL it doesn't work that easily.
At
54.7 you just need to have two pairs of eyes, nothing more, so that's not a big deal.
54.8 is usually, where my game ends making me mad, because after that there would be only one hard PD level (54.11 so to say) before the junction (54.14). At 54.8 the pineapple does the job again stunning you after the strawberry or someone else finishes you.
dragon i f you do that it is flying with more speed for a moment xD
today 
... FB killed me before I get the Hell.1 crystal. Had 2 dumba$$ deaths on Hell.2, therefore I didn't get the crystal (but I think it payed off later). Didn't go for 
so no 250k + other crystals there... No crystal at 62.2, no PD64, PD77 and PD82 at all! It turned out that 81 order is wrong! And since it's 7AM I performed very bad at lvl 95, 96 and 97, died at 97.0... no C5 item all game... and still I think it's the wrong thread I'm writing in
