You can get kicked out at 7/10 or other values, the counter is not properly implemented, but I will try to fix it.
When you are thrown out of the library/work means that you have used up the number of available spellings of words (at work you can just restart, and for the library you need to earn money again (if you do not have any left)). In the library it is made for the fact that it would be impossible to pass the game by earning only 10$ at work, and had to constantly work at work, and in the office I do not know why the limitation on the number of words :D.
If you throw you out on the hack the final computer, then there is an error (in the decryption) and you need to try again (you can go there as many times as you want, nothing will be spent), but to use the computer you need to get 2 points of knowledge (upper right corner), it will take a long time to do, then I will make learning faster.
Have a good game and thanks again for the review ^-^
