I don't know but I just downloaded it and played it. you do have to extract the folder to play. as long as you have a windows PC your good to go.
Also to extract the file you have to right click on the zipped folder and than left click on "extract". Once you have done that open the extracted folder (it should just show up under the zipped file.) you click on "not minecraft dont sue me pls" and the game should start.
