There were a few mistakes, maybe you should try to correct them.. it doesn't bother me that much but it's a little annoying.

But your OS was great! There weren't much details and explainations and that was what I liked best. Most of the times FF's are really boring and lifeless without details but here it just... fit. So very well done! :D

cute,i really liked it,and well,a little sad the fact that they hide,you know,for the sake of stupid pride,and all that .but i liked it..good job
