Level 755 is too hard the best I could only get three 7 letter words and it's getting less interest to keep trying but no luck. I think it's time to quit this game.
Replayed now, passed on first try with default +2 Cowboy Mouse, 9 words of length 7 obtained with 1 move left despite one bomb exploding.
Due to the large amount of mousetraps it's key to start wiping them out early, so build 6- or even 5-letter words and set them off as soon as possible to remove traps and gain precious space.
Bombs are a secondary issue as they explode after many moves, so don't get crazy if you can't remove them quickly from the board (well I've been a bit too lax in my game on this point ).
Once enough traps are gone, be patient and look for 7's - didn't have much trouble. If you REALLY can't find 7's, get 4's so you have crowns and can use them to reach 7 with shorter words.
Don't bother starting with crown boosters as with the packed board you'll likely be wasting them on short words while taking out traps.
another approach ... create crowns ... then blast crowns ... blasted crowns are returned to the board ... you can find screenshots here ... open in a new tab or a new window ... http://www.screenshotabe.com/index.php

bye bye
After uncountable attempts, I have passed it eventually!!!!!
755 is not easy ... remember this ... crowns add to a word's length ... when included with the word the crown will be consumed ... when a word is created that includes a blaster - any crown that is hit by the blaster adds to the word's length and is returned to the board ... it is possible to make 9 crowns when playing level 755 ... keep blasting crowns so that there are many left at the end of the game ... before making a play look at each blaster and see how many crowns can be hit
... oops did not see where you passed(read the gray comment) ... congrats
