Thank you mate
As I promised, here is ZIP file containing camera mod.
You just put all of the files into the game folder where .exe file is, in example, mine is:
C:\program files (x86)\new folder\PURE ONYX_0.100.0
It should look like in the photo
.
After launching the game you should see a bar on the top, you can select "Freecam" and change time scale of the game.
Try to open It with F7 if It isn't on the screen right away.
Let me know if this works, I had some trouble getting It to work on a copy.
If It doesn't work, I will need to think some more about this.
