Please, put the actual pc time to the alarm clocks in the bedrooms!
This supposed small detail would have a very big effect on feeling real in the generation zero world.
Of course, the time would not fit to the day/night sequence of the game but the 00:00 do not as well.
I don’t think this fact would disturb, as it just would look like the clock is wrong. And by the way, the player would have the own day time more in focus what maybe would help to not spend the whole night in front of the pc (GZ have fully the potential to do so).
The radio beacon disappears when restarting the game. This makes it nearly useless (in solo mode).
Make it permanent until a second one is placed on another place.
Let the player see his own body (feets).
Include a slingshot (with stones as infinite ammo) as tool for distraction.
Apart from that the game is great! The best I have played since a long time! don’t let you make unsettle by the critics that comes from the main stream.
