Haha, theres no code xD
I would be happy to help.
I made a minecraft game before, so I’ll post it here.

CONTROLS:
Left and right to move (left and right)
Space to jump
Up to jump and put a block underneath yourself
Down is to dig down
Left+B or Right+B to mine sideways

I don’t mind if you steal a whole bunch of the code or art, so if you want you can!
