Arrow keys to move. Space to jump. Press up arrow when on a ladder to go up it. If you touch the edge of the screen you go to a new world. Click on the screen to place a block. Press keys 1,2,3,4,5 to change what type of block you are placing. Touch a block and press "d" to delete it. You can only delete blocks that you have already placed. If you want a blank world, press "a"
I made a version of Minecraft that is not as good, but is has a bigger world and better block placement. http://scratch.mit.edu/projects/44747196/
