# Feedback for puzzle i made up

So I made this puzzle where you have words that branch off into other words. For example:

The blue letters you take and move it on to the next blank space, still putting it in order:

For example, FUN and RAM would get RUN, not URN, UNR, NUR, RNU or NRU.

Here is the complete puzzle:

• I suppose it's a little bit unclear what the exact mechanism for color changes between the letters is. Also, how did the words go from 3 letters to 4 letters - that doesn't seem like a conventional word-ladder? – Avi Jan 18 '20 at 22:39
• From the explanation, the word on the right will be FED and its last two letters are shown at the bottom as ED. So do the other two letters at the bottom form two of the letters on the left, making the first word on the left either *AP or AP* ? – Weather Vane Jan 18 '20 at 22:50
• What is the connection between the left and right halves of the puzzle? I can see that the word below FOE must be *EE, and that the word above MAD must be RO* but how do you get the * letters from the other half of the diagram? – Weather Vane Jan 18 '20 at 22:55
• Looks like an interesting idea. Are you asking for us to solve it too? Or has this been solved previously? – Earlien Jan 18 '20 at 23:23
• Visually, I'd swap the blue and the black or choose a different colour. The black pops more than the chosen blue. – Dr Xorile Jan 19 '20 at 16:50

Bar the unclearness of the puzzle itself, here's a potential solution:

         NAE FOE
/       \
NAY         FEE
/   \       /   \
/     SAY SEE     \
NAP                   FED
\  \     YUM ROB     /  /
\  \   /       \   /  /
\  YUP         ROD  /
\    \       /    /
\    MAP MAD    /
\____     ____/
\   /
_AP+_ED


Here're the assumptions I made:

1. Collisions between blue letters and normal letters break in favor of blue
2. Collisions between purple letters and other letters break in favor of purple
3. In collisions between letters of equal tier ($$purple > blue > normal$$), either may be chosen
4. For the final selection, the outermost tiles select their last 2 letters
5. Purple letters may only be present in the outermost two words and the final answer
