Now I learned something new! I didn't know there was a new Construct out. That's really cool. It could be the right fit for your game project.
However, when I talk about HTML and JavaScript, I'm talking about coding from scratch. Just a browser and your favorite text editor. I recommend Notepad++... https://notepad-plus-plus.org/ and start with W3Schools... https://www.w3schools.com/
The layout and control you have with webpages in regards to text and images is phenomenal. Use HTML and CSS to create your UI layout. Then start making buttons that populate and calculate stuff with JavaScript. Browsers have debuggers built in that will tell you which line any JavaScript errors occur in.
There is a neat program called Twine... https://twinery.org/ ...and it let's you make text adventures with clickable options to proceed. It's a web application that is both online and downloadable. It will quickly let you map out a story (or areas of your game). With Twine, you can use it's native language (default is Harlowe format) to set variables and do simple calculations. You can include custom JavaScript within your Twine game. Try adding a graphic by coding in a basic HTML <IMG> tag. Customize the CSS that controls the look and feel of the game. At the very least, it might be a great tool to help prototype your game with.
Good luck!
