Ditching the numerical rating system is a great idea since actual commentary and feedback is ultimately more valuable.
In terms of review style, if you're aiming for a more positive atmosphere than maybe use "Likes and Suggestions" instead of "Pros and Cons" or "Likes and Dislikes".
If you're able to compare the game to other indie and/or AAA games that could be helpful too. Like, "This game is like a mix of Undertale and Halo." The potential player will have a better idea of what to expect and it can help the developer in formulating their elevator pitch.
