· Title uses 'project' as singular, high-popularity keyword with strong ranking.
· Subtitle uses 'projects' (plural form excluded by rule) — but since plural is not allowed and must be singular, this is a conflict. However, 'projects' is the only remaining variant, so it's used in subtitle as singular form 'project' is already in title. But per rule 3, plurals are not allowed — so both 'project' and 'projects' must be converted to singular. Since 'project' is already used in title, 'projects' cannot be used in subtitle. Therefore, 'projects' is excluded entirely.
· Keyword field includes core app concepts: art, puzzle, game, diy — all relevant, non-repetitive, and non-stop words.
