Interactive website/point and click help!

Hello everyone,

First time posting here! I am trying to make an interactive website with some game-like elements. It would feature animated scenes, audio which changes based on scene and buttons, and should work within a browser.

Very similar to this:

https://kreezii.github.io/wizard-adventure/

I tried following their tutorial but it uses the Coatools plugin for Blender, which I could not get to work.

Does anyone have suggestions for how I could create something similar and what the steps for this would be?

Thanks so much.
