Russians do smile, a lot. The thing is, Russians are not fake nor pretentious neither they like ppl that are like that. They're lovely simple down to earth ppl and they don't take any kind of BS. If you "act", they will not smile back. I love that!!
in the credits u should put the link of Lucas as the first one, since this is basically a rip of from the Codrops demo. (like most if not all the things u post)
