I was looking for a small murder mystery program, and I found this gem of a submission to js13kGames in 2021.

• Blanks Detective (2021) — Procedural Deduction Mystery
• Developer: Daniel Cohen
• Zip Size: 12.38 KB
• Format: A logic-grid mystery/detective game featuring procedurally generated crime cases. You cross-reference clues and fill out board deduction matrices (similar to Clue) to catch criminals.

Impressively, the game manages to include text-to-speech within its 13 KB budget. It is made possible with the Native Web Speech API. Here is a quick demo, it works so well!
