Well I played some more with different answers, and I don't find the way to get where I can fight something with space, or move around with the arrow keys, I only talk to Jason, untill he thinks he hass enough data, and tells me to send him in email...
Also, when I reach an ending, with the credits, there's no way to exit normally, I'm forced to use the task manager...
But this is interesting... Which game gave you an idea to this?
