such busy days

Hey,
there are a couple of busy days of mind, and I am tied up so much, and almost I get less time, now I am going to university for teaching, and I related with my students. and we have started a new project that I love it too, and I am so happy with my colleague. I didn't pay attention to my English these days and I am sorry about it, really sorry, and I am concern about my friend who lives in Malaysia, he is going to makes himself problem I guess, and he removed his weblog.
we have done some things new in this project and I designed a new facial animation steers on our characters that it makes able to us to control our character's face in all positions. I love it, and I know it will make us problems, but it doesn't matter, it used to be always and always.
OK, lets to the our class post/

you ought to play this game, it's really good,

and there are a couple of sentences so rest of them for next,
