You have done a good job. I would say that there are enough ‘clones’ of minecraft for it to be considered a genre. I am also making such a thing. I don’t want to post links here since I’m new, but you can check my game out by searching “simcube game” on google. Its focus is primarily realistic and complex simulation. There is an in game computer that can be programed to display png graphics on an in-game external screen (a cube separate from the computer itself. I am now currently working on these things called surveyors that will allow structures to be encoded onto an in-game virtual disc, which can also be used to build the same structure within the surveyor GUI. I am going to add villages next, that will have traders and builders. The builders will be able to be given a disc with a structure encoded onto it, and will automatically build it upon the village population reaching a certain amount. It is really fun to play, and I am enjoying the process of making it.
