Simple Easy Fun, I love those tiny dev note humor! ^^
But I spot some um.. bug? that you can grab multiple blocks at the same time if you scroll your mouse wheel while hovering on them, but it might not be a big problem tho
Also when the block got destroyed when it's not supposed to be somewhere, it could have some effect of getting destroyed to give the player some feeling of "Yay I did something that they don't want me to do" stuff
Anyways, The game is Awesome! > v<
