Cool idea but I couldn't figure out how the block breaking works.

Interesting concept, I like the combination of spelunking and delivering giving the player agency in how to deliver the mail. Wish there was some sound to go along. You did well though!

Fun concept, i always wanted to be a miner *and* a mailman! Although, sometimes you can't mine some block close to you. Also you can't jump on the bottom world barier.
