Shuffle the texture of blocks, change grass blocks to glass blocks, iron blocks to diamond blocks, and so on.
The created resource pack is saved in the internal storage, so if the same version of Minecraft is installed on the same smartphone or tablet, it will be automatically imported when the resource pack is executed.

[How to use]

② Save the resource pack.
③ As the save destination is displayed in the dialog, close the application, search for "(arbitrary name).mcpack" from the file manager etc. and open it.
④ Start Micra, activate the resource pack and play.
