I mean, I’ve been releasing updates at a similar rate since 2020, so given the fact that the outliers don’t have file changes, it’s probably that. I mean it could be anything, I guess, but as far as I know, releasing an update once a month or so and getting a bump is not unusual. Also, you don’t fly to the tippity top of the recent category when you get a bump. I don’t know exactly how it works, but there’s a new and popular tab that you jump up on, and that bump also gives you a bump on popular as a knock-on effect.
Also, the most recent time this happened was about a month ago and certainly other games have gotten bumped since then, so no, they didn’t just stop doing that altogether because they’re busy.
