It might be a few months before it's launched, but much, much better characters are coming (the current one are just placeholders and we're a little embarrassed by them). Glasses are just the beginning!
Glasses would be nice indeed. Also, clothes, facial hair and a few choices for body types would be great. I'd love to make my character stumpy and with a big moustache so I can mirror my real self a little more. xD
Also, you shouldn't be embarrased by the current characters... I think they look really funny (in a good way) and quite follow up on the general game's "feel". :)
Indeed, the current characters are quite charming. There is no better way to describe them, you look and you just can't help but get a tiny little smirk.
