I must say this is a decent start so far, but I feel like there's some constructive critique needed.
(Also, I'm uncertain about your plans so please take these as some recommendations as you please)
1. Night structure
Don't get me wrong I think the nights are fine, but it's currently hard to indicate what night it is or even choose an "unlocked" night.
Do you plan to add extra features that involve nights?
2. Visibility
I feel like there should be some small changes to how we see within the (office) cam room, for example maybe adding some windows or such near the doors, also the lighting during the game over sex scenes seems a bit dim making it hard to see enough details.
3. Story(line)
(If you plan to continue this game as its own thing or maybe later on a remake, this might apply.)
Do you have a story planned already for this game?
Will there be more animatronics?
4. Extra features?
I saw the NSFW content preference popup & somewhat found it useful but rather out of place, if possible add a settings/extras option in the main menu for such things, especially to make it easier for anyone to adjust whatever settings (sound volume, screen size, brightness, etc) you provide & maybe provide access to other features in the extra menu (special/custom nights, extra scenes/content, etc).
Again this is just some feedback, thx for sharing your project regardless of its condition.
(Also I did my best to list the top things that I was thinking during my first session playing)
