The test had a point-based system, where the player could acquire points from killing some of the game's first mobs. It was a very early version of the game mode. The release of Survival mode in Classic was conducted in a series of tests named Survival Test.
Creative and later Survival game modes were introduced in this phase. This phase was commonly named 'alpha' during its development until June 28, 2010, when a blog post retroactively labeled it as 'Minecraft Classic'. Classic was the second phase in the development cycle of Minecraft ( Java Edition), following pre-classic and preceding Indev, and was the first Minecraft development stage to have some of its versions released to the public.
