2 EXP

Having someone "thank" you for a helpful forum post: 2 EXP
That's all you have to do? Well... that sounds easy enough, i'll try to do all of this and see how far i go! Thanks for all the help. Though i do have one question: What do you profit from leveling up, as in, do you just add stuff to you're avatar and that's it? or: you can earn coins or upgrades for certain games.... Answer that from me and i'll thank you more times if i can.

1.click sneak in then press shrink ray
2.click sneak in then press the pick
3.click sneak in then press jumble hoppers
4.click sneak in then press anti-gravity cap
5.click sneak in then press liquidificator

do you think you can change it from 2EXP to 3EXP because it is the easiest way to level up but only ten uses, walkthroughs are the best but there is basically no way to make one that hasn't already been made, likes are to hard to get unless someone bothers to read your post but it also has to be smart, someone also has to like a comment on a game but it may be stupid and someone may report you and they get EXP and some of us don't even have G+
