Nightmare of Game Development

You are a game devloper who lack of sleep. When the deadline has come, it seems like you get a lot of stress and hallucination.  Dive into a nightmare where his game is full of bugs and never be finished.

Update: 

• 25 Oct 2018 - 6:40 AM EST => Add an invisible wall so you'll not fall out of the map anymore.

Note: 

This game is my nightmare. It still need a lot of update as soon as possible.
**If you can wait until 26 Oct 2018 (Tomorrow) at 7:00 AM EST, I'm gonna release a big update for this game. So, the game will have more thing to do than current version. Including, the real nightmare. :D

Hint:

If you fall from the map, just restart the game. There is a room on the right side. In the room, there are three diskettes that you can put into the computer. Only the game itself can be bootable. You need debugger diskette to remove bug from the game.

Controls:

WADS : Move
Mouse: Rotate View
Left Mouse: Pick up something
E: Use computer
