create a code on csharp using unity(word search game)

I need someone to write a script in c# for me to use on unity. I am building a word search game and i have some code issues. This is what i want: The script should be able to take users input on the new unity gui and output the letters it swiped across when a user swipes across letters. users should be able to swipe in only up-down,down-up, diagonal. not doing this should stop script checking Draw line connecting the selected letters . Just like this [login to view URL] Basic ui should be used. I dont care about design. Just implementation. Please tell me if you need further explanation and add the word cupcake to bid so i know you read this or i wont even chat with you.
