HabitRPG/habitica ? reverse-engineered prompt

I want to build a web app that helps people stick to their habits by turning their life into a role-playing game. The basic idea is a combined to-do list and habit tracker, but with a fun, gamified layer.

When a user completes a real-life task or a daily goal, their in-game character clone should get experience points (XP) to level up and also earn gold. If they fail to do a habit or do something they're trying to avoid, their character should lose health points (HP). There should also be a shop where users can spend their gold on virtual items for their character, like new armor, weapons, or other fun customizations. It’s all about making self-improvement feel like an adventure. Use a modern JavaScript stack for this.
