Developed this in Godot over the course of a few months in Summer 2022 and got stuck redefining the scope of the project.  Tossing an HTML version up here so I can more easily show it to people.  Never done web app development and didn't particularly optimize it so I hope it works.  (If you press quit on the main menu, you need to reload the page to play again.)

Tutorial isn't in the game so read this before playing

From the Simple difficulty intro cutscene script:

Welcome to Nycis Incarceratory Systems.  This is an assessment of your ability to take on a real shift at one of our facilities.  Your task is to simply press the buttons you see onscreen.

On a real shift, each digital button corresponds to a specific enclosure in the facility you work in, and clicking it resets the locking mechanism for a period.

As you work, you will gain access to more enclosures so as to not immediately overwhelm people just starting their shift.

Sometimes, you may run into malfunctions.  In that case, you are expected to open the Maintenance panel and re-enable whatever features have malfunctioned.

While just an assessment, we want you to take this as seriously as if our lives depended on it because, at some point in your assessment, they might.  You may be given control of one of the real lock mechanisms without being explicitly told.

Our locks here at NIS are on a timer that slowly counts down to the door unlocking, either due to a mechanical issue or interference from the prisoner. This is estimated via a patented computer algorithm that allows us to project how long until said lock will hold out.

We DO NOT have our locks on literal timers, despite what various world governments might claim about our facilities.

The creatures we contain are extremely dangerous and our facilities are underfunded by said world governments, who do not care for the safety of their constituents enough to allow us to properly contain these creatures.

With that said, I’d like to thank you on behalf of humanity for volunteering to take on such a vital position at a NIS facility, whether you are full-time, just covering a shift, or something in between.

Nycis Incarceratory Systems thanks you and wishes you luck on your assessment.

There's some other stuff in the later difficulties but that should hopefully cover the basics.  You'll probably figure it out.  Good luck, I guess?  Thanks for checking out my little prototype.  Oh, also, I don't think Expert is possible to beat but feel free to try it and let me know how it goes.
