Hello, may I ask what tools and technologies you used to make this game, and how you developed it? I’m really interested in this game and would like to try creating a similar one with comparable systems, but in a different setting.
I'm not affiliated with the dev team, but this game was made with Twine, which is free! Just be sure to use a version of Twine that's currently compatible with Sugarcube, as it will allow you to use Javascript.
