Yes, it's a clone but who cares? the music adds a reward to the game...
besides which to all those lazy-ass haters YOU make a COMPLETELY original game. give it a try it's harder than it looks...
(on the "dirt wall debate") if the reason the creeper ignores dirt is because it has high entropy (low order) the the moment it gets placed in an ordered structure (like a wall) then the dirt suddenly has low entropy and is as much of a target as the energon, plus energon is easier to build
