Minecraft wiki entry for Demo_mode, associated text: Worlds could not be saved. Upon clicking Play, players would be asked if they wanted to play in Creative or Survival without any world list shown whatsoever. Upon quitting, the world data would not be saved.
Seeds could not be used, as they could in the full version of v0.2.1.
Only 28 of the 49 items in the inventory could be selected. For example, the player was able to use the shovel, the pickaxe and the axe, but not the sword.
The demo can be downloaded again if the same account is used in the App Store/Google Play Store if it was previously deleted from the device. However, on iOS devices, the app refuses to open on iOS 11 or later, due to the lack of a 64-bit binary.
Multiplayer was available, but only through LAN.
