ideas

maybe your subconcious had already picked up on the solution to how to improve the game but your concious brain had not fully played it over or taken notice to it. Then in your dream the answers were revealed again through your subconcious mind.

maybe what you programmed what was completly random crap that your subconcious associated with something and then it snapped to you.

maybe an alien implanted the anwsers to improve the game inside your head at night.

maybe the game doesn't exist

I give up..
