Brotato and Vampire Survivors are both set to release new DLC. Soon after, Darkchaser:Battletide and Jotunnslayer will be launching their official versions. There's so much to play!
I'm guessing you're referring to Vampire Survivors, which does have the Bullet Hell tag on Steam.
I agree that it's not a traditional Bullet Hell, but there are also three other games listed in this post. Seems like OP is just excited, no need to be rude.
Vampire Survivors' genre has been coined 'Bullet Heaven', literally the opposite of bullet hell. The fact that it has the tag on Steam is kind of meaningless. Monster Hunter: Wilds' Steam Page has the Dating Sim tag, but I'm willing to bet I won't get to romance a Rathalos.
