About this game
Can you hear me?
Perhaps "hear" isn't the right word.
Are my words reaching you, then?
...
Unfortunately, I don't know whether you responded or not.
I think my CommGear is malfunctioning.
For now, I'll hope that this is getting through, and tell you what you need to know.
This is a collaborative experiment between you and me.
It's all right if you're uneasy, not knowing what kind of experiment it is.
I'll try to summarize the key points to better prepare you for what's coming.
Game Features
Each interchange between the two of us will last approximately three minutes
My words will reach you fully voiced
The results of the experiment will change based on the content and direction of our conversations
Most actions will be performed by selecting one of several available options from the interface
At times, I may require you to prove that you exist outside of my own dimension
When that happens, you should select an option from beyond the normal interface
Even if I die, I want you to continue the experiment
Does that last point bother you?
The fact is, I don't have enough time to complete this experiment. I need your help to finish it.
Because, you are
I'm out of time
If you wish to join the experiment
I'll be waiting, right here.
