Edit: Upon talking to others I decided to replay and pay more attention to even the smallest details. I found some variations I hadn't noticed before and some funny patterns in the small text.
This is a darkly humorous game about amazon reviews for a portable battery-operated mini chainsaw.
Each review describes how the person used it, ranging from reasonable to typical-online-customer to dangerous to surreal. You can rate the ratings as helpful or report them.
The story progresses over time, advancing to a final culmination.
Someone on itch said they figured out how to get two different endings, and the creator confirmed that choices matter, but I don't know how. The first time, I rated all the nice ratings helpful and all the murder ratings 'report'; the second time, I reported everything; the third time, I rated everything 'helpful'. I got the same ending both times, but the last time the screen was dark with creepy music (but the text was the same). If anyone knows how to get multiple endings, I'd be interested!
