jeez level 58 took me forever. I didn't have to try any level more than twice (the final boss took about 4 or 5 tries), but level 58 was so cheap. literally took me over an hour. The giant sphere weapon the key to beating 58 for me, and Duck + Big laser + lock on laser did the trick for the final boss.
