you know there should be a "clever" way to beat level 58. weapons have a very short duration they can fire, so you have to switch all the time with the same fingers what you should be dodging with. freeze time+bfg+lightning worked for me, moving diagonally from top left to bottom right or on the other diagonal, as thats the only way to dodge the planes spawning on the edges. took like one and a half hour trying with this (i was close as 1 sec to level end 3 times, and the last run i was simply lucky not getting into bad situations). someone could make a skip-58 mod for this game.
