I forgot to mention, regarding feedback, also about soundtracks, which is very important. Sound in the office, as it gets very annoying, the sound of phone calls without anything in the background... Alarms from creatures when they notice us in the game, could be a very hot moan or laughter. Regarding the soundtrack, I would suggest that they open the possibility of having the game access your music files, seriously, it would be really cool. Possibility to change the controls both on the keyboard and on a joystick, and also have the game in my language Pt Br, as the Brazilian community is strong when it comes to games. Nintendo, the number one sinner, is already rethinking this concept. If I remember anything else that could contribute to this game, I will mention it with possibilities and constructive criticism.
