Could you build this?
Partial The app logic (problem bank, spaced repetition, hint ladder) is buildable with vibe coding. The visual novel content, including voiced characters, art, and scripts, plus licensing for the 2,000-problem bank, needs creative production well beyond coding.
What it would actually take: Build the study engine as a web or mobile app with a problem database, spaced repetition scheduler, and progressive hint system. The hard parts are producing the visual novel content (character art, voice acting, narrative scripts and branching relationship logic) and securing rights to the problem catalog. Those need artists, writers, voice actors, and legal review.
