Change name

Hi !

I registered a few days ago under the name of Green Pumkin Pie with Melted Peanut in Tasty Chickpea Jam. After playing a few hours (around 100 games), I wanted to buy a color, and bought jungle. But I just realized that I've misspelled my name (I spelled Pumkin), and I would like to add the missing 'p' (I don't want to create a new account because I already bought jungle). Is it possible ?
Sorry for my bad English, I'm from France ^^'

Thanks for reading
