Greetings, I'm an expert game developer and I have been developing games for more than a year. I have already built couple of games with unity from scratch and some of them are attached to my portfolio, others are NDA signed,but I can provide screenshot as sample.
I have read your requirement but there are a couple of games named "Hex" out there and since there are no video attached I can't be sure of which one you mean. I would like to discuss more about the project so feel free to knock me anytime. Have a nice day.
