Where is the game? I can't see the game, all I see is a wallet address of yours, also the prize is not enough for a programmer, time is important to a programmer. Why would you want us to donate to you? You had your services there and you still want donation?
It's a puzzle game. The start of the game is the QR code (I think) Maybe some programmers are bored, and want to have some fun while utilizing their skills with a chance of a small prize. Programmers don't work 24/7 as far as I know. He wants people to donate to him so he can keep funding these games, or maybe they enjoyed the game and wanted to support him.
