Five Hours on Copper-9 is one of my favorite FNAF Fan Games now. Not without issues, but still. I think the presentation, and controls are stellar. If I were to complain about something, it would be the cameras. The cameras don't really have a use, aside from J, and the camera panning is not my favorite. Other than that, this is a stellar game. Using the SFM models doesn't change the utter terror I felt while playing this demo. Can't wait for the full thing!
8.5/10. Really fun, but some minor issues that don't affect the game too much.
Side note: Can't wait to see what's up with the lore in this little game, and to see who or what gets added next.
