M&M's Shell Shocked for Playstation; accidentally discovered cheat mode?

So i fall into the chocolate on this one level, and magically disappear! so the screen is moving back and forth, like the graphics are glitched and it keeps taking me back and forth through the level, except the yellow m&m isn't there, and so i pressed a bunch of random ons and a screen came up that was green i think, and it gave me options like sound options and run options and then there was the God option. so i turned that on and discovered that i could skip levels, give myself lives, make myself appear when i dissapear, and go through anything that would usually hurt me. me and my brother even discovered a level where your in a spaceship and you fly threw and theres flying chickens and boxes everywhere. problem is, we got to the end of the flying level and now the m&m's are automatically giving lives on their own! at the top left hand corner, it keeps receiving m&m's from the bottom right hand corner, which h a pic of the yellow m&m guy. bottom left hand corner is a random 0 with a red m&m next to it, and every time the upper left hand corner receives its m&m's, the top right hand corner gets another life. well it's gonna keep going until the upper right is at 999 i think. has this ever happened to anybody?
