No problem man, your work is great. I don't know If I'm going to splurge just yet, I was just getting an idea. My idea however, is inspired by left4dead, a zombie game for PC and 360. The character being tickled would be Zoey, the one girl out of the 4 characters. The other 3 characters, Francis, Bill, and Louis would be tickling her. The general outline would be Francis holding one foot in a sort of arm-lock tickling it (bare, shoe removed) while she was kicking him in the back with her other shoe'd foot. Bill would be holding her arms stretched behind her while Louis would be kind of crouching over her tickling her under-arms. While a zombie would be peering in through the safe room door window (it's a metal door with a window that has metal bars).
Really only the foot-tickling part with Francis is what I care about, everything else would really be up to you. Take your time, because as I said I'm not sure if I want to spend the money now, but please consider it.
