How long will it take: No idea, at this rate the clesest to a release date I could give is March.
What will be the controls:
•Vent lights: Dpad left/right
•Flashlight: A
•Camera: Dpad down
•Mute call: Dpad up
•Freddy mask: B
•Wind up music box: Dpad up while in cam 11
The gamepad controls will be mapped to a keyboard, but I don't know how yet.
How completed is it: About 12%, I'm currently working on the craphical assets, which takes a lot of time.
I hope that answers all your questions!
