This is a great recreation of Minecraft. Really impressive, I wouldn't know it's a knockoff unless I would've played the real deal.
Tho you should worry about copyright strikes ;)
On top of base rules it features the deadly zone (yellow zone on the map), and 2 new rules:
1. A live cell with exactly two live neighbors will "migrate" to a random adjacent cell
2. Each tile has a 50/50 probability to teleport to a random location on the map, if it is available.
Game is working as intended! :P
