3D Minecraft for TI Nspire CX calculators running Ndless
Thread on omnimaga: http://www.omnimaga.org/ti-nspire-projects/ngl-a-fast-(enough)-3d-engine-for-the-nspire/

Simply download the crafti.tns file from the latest release in the releases section in GitHub and copy it over to your calculator. Then, simply locate the copied crafti.tns file on your calculator, and run it

NOTE: Crafti requires a jailbroken calculator to run and will not work without Ndless

You can use custom texture packs with Crafti!
To learn how to do it and download the Crafti-specific texture format and converter script, simply view the following repo: https://github.com/Bluebotlaboratories/crafti-textures

Move around using the numpad: 8-4-6-2
Jump using 5
Switch the current inventory slot with 1 and 3
Open a list of blocks with "." (Screenshot with CTRL+.) Set the current inventory slot with 5 while the block list is open
Put a block down with 7 (or select) and destroy a block with 9
Open the menu with menu, move the cursor with 8-2 and select it with 5
The +/- buttons let you change the render distance
ESC/HOME is a shortcut for "Save & Exit"

Note: This is experimental and may not work as expected

Move around using WASD like standard minecraft
Jump using space
Switch the current inventory slot with Z and C
Open a list of blocks with E (screenshots are possible with CTRL+E and CTRL+.)

Place a block with 7, select or LEFT MOUSE CLICK
Remove a block with 9 or Q
+/- let you change the render distance
Open the menu with R, move the cursor with the arrow keys and select it with left click or enter
Menus can also be navigated with WASD

ESC is still a shortcut for "Save & Exit"

Crafti doesn't use floats, so there will be some graphical inaccuracies.
