I read the READ ME FIRST txt file but I didn't think it really explained what I was supposed to do very well. So I ran it and pressed some buttons on my numeric keypad and eventually figured out what to do. I think.
From what I understand of it, pressing any of the numpad numbers (besides 5 and 0) moves me in that direction. Pressing 5 will send out the sonar which tells me how far away I am from something else. I don't know if this is the gate to the next level or the UE who is trying to kill me. It's just a matter of playing hot/cold after that. Move one direction and see if the number is lower or higher. If it's higher, move the opposite way.Seems each time I got the number to 0 I died and got the BSOD. I don't know if that was the good ending or the bad ending.
The voice numbers were hard to understand most of the time. It seemed like the audio files didn't play out to completion so I got part of a number but not the whole thing. Also, sometimes it beeped at me a few times, which I concluded meant that I was up against some sort of wall and could not move in that direction anymore. I figured it was a box/rectangle, so once I was against that wall I never tried to move in that direction again.
I also never tried pressing the numpad 0. I hope that wasn't supposed to do anything to help me.
