I think the message was pretty simple actually
You were born kind of like Adam, and you were given an infinite world to do as you pleased except for the one tiny black dot that represents the fruit of knowledge/sin. You and the pink square, Eve, had eaten the fruit so when you both became one(the blocks combining) you had children, who were corrupted by sin when you encountered the dot again. You were so full of sin that you kept getting more and more sinful.
God said he forgave you, but took you out of this world
Besides that, I really enjoyed this game! I love the music and simplicity to it. Being a religious person myself, the message was very clear from the start. Great job!
