Hello RocketSingh.

The backend was built with NodeJS + MySQL + CoinNode (Litecoin, or Clamcoin), and the frontend is pure HTML, CSS and JS. And the communication is done with Sockets.

For the hosting requirements, i would suggest at least 4GB of RAM to avoid any issues while you sync the coin node, and the Disk side depends in the chosen coin, if you want litecoin then you will need Something like 200GB (172GB for the Node) , if you want the clam version then you can work with 40GB because the node uses close to 16.5GB. The game by itself doesn't consume big resources because the animation happens in the client side.

As an update, today i was working in a new design for the Litecoin Version:


I'm already working on the servers to bring a Demo Version public for all who want to taste them without having to contact me, I hope to have them ready for this week. If not, for sure they will be ready for the next one. And if any one of you wants to test the game now, just send me a message on Telegram, and i will share the link with you.
