It had some bugs, one time I spawned I think on one of the buildings, because I coudln't move at all. Another bug was that I began flying left-right, got stuck in a wall trying to mine a stone. Also the buying menu was a little weird, I had something selected, I pressed S or W, and there were two things selected.

It's a nice idea, but because it's kinda long, not having some background music, or even some sound effects, really dulls the gameplay. Other than that, it's a nice game concept!

I'm impressed you managed to do this in 72h! I had to play quite some time to figure out the mechanics so maybe a few indications would help. Overall great game idea!
