Don't wish to be a spoil sport, but this is th e wording from the OP:
"you have to change a letter to make a new word. you can also add or subtract a letter...try not to repeat!! (you can use proper nouns too!)"
It says change a letter, not rearrange them
It reads as though you can change a letter AND add or subtract a letter (ie in the same go), but I think the actual intent is to do 1 or the other.
Perhaps peace*out can arbitrate.
