Very interesting mechanics at play here! It's very cool to have the spy break out of the ball and move on it's own when you're out of gas (Or touch one of those walls), very creative! It's a shame the code revealing isnt working, I tried clicking the lock since I saw it mentioned on another comment but it kept displaying * despite 100%ing the levels :< If you can post the codes in the comments or somewhere I'd love to play the final level, but regardless, very fun experience! :>
