You might remember this screen shot from a prior tip about Double Dragon for the NES.
I said that I liked walking off the edge of the platform like that because Billy makes a silly face when I do. But was that the wrong thing to do? Page 58 of Compute!'s Guide to Nintendo Games seems to think so, Steven Schwartz writes:
Also, don't just walk off the end of the wall. Jump if you don't want to lose life points.
I tested this by walking up to that same ledge and walking right off a dozen times in a row. The result? No life lost.
So go ahead and make Billy pull that silly face by walking off that wall, it won't cost any life points.
Sorry, Steven.
