Uh as stated on the N8 forums, my friend helped me to buy this game but unfortunately, his name became the username for this account. So is there any way to change this email/username?

EDIT: I'm probs being dumb, but where is the sprite sheet?

Yep, it can be changed.
send me an email with the request and I'll make it so, and send you an email when its done.

Sprites haven't been uploaded yet, only because I was changing them a lot... but I'll try to upload them all today

Woo! Will email when I'm free, later today.
