You focus on the height slider,
Currently it says "169"
Thats not much- you say
-time to grow up
You slide it to "185" you've always dreamt of this height
You don't feel any changes for 5 seconds, then you see your legs getting longer, your arms are getting longer too, your hands get big and your fingers long , everything in you grows, your jeans and shirt get really tight, you quickly take them off to avoid suffocation or getting your junk crushed, you are in your pants only, you notice that your penis got bigger too, everything is proportional except your muscles, you suddenly feel weak, so you move the muscle slider to the right, after few seconds your arms are pumping up, your belly is forming a nice six pack and your chest is significantly bigger from the muscles, your legs have nice calves. You look in the mirror, you are nicely built, it's a dream come true for you, lets see what else this thing has got...
