Old gameloft games like your pic are made on Java (different to javascript), and built for J2ME platforms. It's an outdated technology, but if you want to develop for mobile using J2ME, here's a tutorial: https://www.youtube.com/watch?v=AMI7B-K0x3g

You want to make WEB games though, which J2ME isn't built for. Can't use raw HTML since it's very limited, but there is a variety of other ways to do this. You can still make old j2me looking games using these newer methods.

If you dont want to bother with code try GDevelop:

If you don't mind learning to code, try Javascript + a framework of your choosing:
- Kaplay (Easy to learn, may be harder to make complex games, no 3d)

- Phaser (Slightly harder to learn, but better known, and better with complex games, has 3d)
