That's a type of review. A review that is very personal and about why something resonates with that person is just as valid as reviews that are directed at an audience. Reviews that treat games as something to experience rather than purely something to buy are importantI think the idea that it's okay to bring the pandemic into the review stems from a fundamental misunderstanding of what a review is. A review in a professional publication isn't simply an exploration of the reviewer's mental state or subjective experience of the game. We already have user reviews for that. What do game journalists add then?
A professional review is one that aims to help potential players decide if the game is for them, and if it's good. That's the entire philosophy behind Karak's Buy/Rent/Wait For Sale system. As such, you, as a reviewer, are free to feel whatever you felt when playing the game, but when reviewing it, you have to think of yourself as a service provider to potential buyers. You aren't writing your autobiography.
I often find that deeply personal impressions are far more informative as to why a game is unique or interesting
