Here's a glitch I happened to exploit while playing Mr. Do! on ColecoVision (ColEm emulator):
I was on scene 4, and the last Alphamonster I needed to go after was the "E" one to spell out "EXTRA" for getting an extra life. But just as I was about to power ball him, a blue Muncher suddenly dropped an apple down my path, crushing not only the Alphamonster, but also me and a Badguy. However, instead of going to the green Extra Life award screen, I instead lost my present life, and after game play resumed, all the letters in the word "EXTRA" became red! This means no Alphamonsters and thus no further opportunities for getting extra lives unless you reset your game! A screenshot of my experience is seen below for you.
Have any of you tried this glitch at least once?
