It's in the output above. Structure and reasoning:
Opens with a hook, not a feature list. "Small enough to finish on a bus ride" says what a 5×6 board is for.
Reverse and Pop-Out get a full sentence each. They're the differentiators and neither is guessable from the name — "connect four and you lose" does more work than any adjective.
The AI levels are described by behaviour, not adjectives. "Medium blocks you" tells you more than "medium difficulty".
Screen-reader support gets its own line. Almost no casual game says this, and the people it matters to search for it.
The ad is disclosed plainly. Reviewers and users both prefer finding it in the description rather than after installing.
Connect four on a 5x6 board. Pass and play, or take on four levels of AI.
