I think bullet heaven works in the sense that you spray the bullets, but it is also a swarm survivor too so I can agree with that as well.
I don’t believe it was the first, but I do believe it was the one that brought the genre to the spotlight. Since Vampire survivors came out the genre has taken off and we’ve seen a great many takes on it which personally, I’ve enjoyed. I find the rather short gameplay nice for fitting into tight schedules and non-commitment gameplay
The YouTuber “Wanderbots” covers a ton of games akin to Vampire survivors and the genre has a pseudo name of “bullet heaven” (opposite of a bullet hell). Plenty of amazing ones like “Death must die” though I cannot remember all the names off the top of my head, just take a look through the videos and I’m sure you’ll find a ton
I bought it the day before the 60% off great game but also RIP
The cameras are usually nice enough for using as a dash cam if you drive. I use one of mine for a media device around the house, kitchen aid etc. I also use an old one for keeping my current one free of boatware, extra apps, and ensuring privacy on my carry phone (by not having anything google or tacking/data harvesting if I can help it).
Outside of that you could look into using them as potential network devices, DNS ad blockers, etc. I haven’t looked recently but using one as a casting device receiver for TV would be awesome over a Chromecast or the like. But not sure how those projects are going
Oh it’s 100% inspired by TA, I played that game so much as a kid and this one is it’s spiritual successor IMO
