Mine the blocks under him (Patreon)

You mine a block under him. Unfortunately there's just another solid block there, so all you've done is make him shorter. I get what you were going for though, it would've been funny.

The miner character punches you in the shin.

You are now careening through the air. You're on collision course with the butterfly, and behind the butterfly is a cliff. You cartoonishly left the pickaxe in the air, but you still have the knife.

What do you do?
