Options Menu

The first version of the options menu originally had only toggles for aspect ratio, full screen, perspective and menu theme. Later on, toggle for subtitles language, subtitles, and a scrapped forced subtitles toggle were added.

Power Outage

Nightmare Freddy looked like he was looking down during early development. His power outage image was redone because of that.

Cameras

Cam 3 originally had a poster of Shadow Toy Chica (fan-made character) instead of El Chip with a pillow/piñata Freddy.

And Cam 5 originally had posters of Chocolate Springtrap (another fan-made character) and Shadow Bonnie/RWQFSFASXC instead of the springlock characters and the SB characters.

Extra Menu

The Extra menu originally had the Back button on the bottom right, instead of on the bottom left. The character name was above the Back button.

Pause Menu

The pause menu (which was later removed from the game due to it causing bugs on the Android version with the new subtitles system introduced on update 1.6) originally used the Esc key on the keyboard to resume after pausing, and Backspace to go back to the main menu.

Radar Cheat

The icons that show up on the camera map when the radar cheat is enabled originally used solid squares. These were obviously placeholders, and were replaced with the proper character head icons shortly after.
