Normally, when you jump and try to mine a block wich is out of range, it will just reset, but in this version it can be mined

1) Place a block a few blocks on top of you, but you can only mine it when you jump

2) jump and hold the attack button

3) if you release the button the block will be in a mining state

4) if you mine it while it's in a mining state, it will reset
