Brotato !

Halls of Torment gets my vote. As usual with the genre it's pretty grindy so I lost interest, but it's probably the best vampire survivors-like I've tried yet. Works flawlessly on Proton btw.

What about Risk of Rain 2 or Synthetic?

Is bullet heaven the name for a bullet hell with character progression? Cuz that feels about right to me, lol. I loved bullet hell games as a kid, but I just can't anymore on the ones that require me to build my own skillset to do well at them. I'd rather just put in the time now to make my character good at them. I find myself playing all the "used to be hard game type but now has rpg mechanics" nowadays.

Basically the "roguelite" to their original "roguelike". Like yeah your own skill still helps, but all it does is saves time now, you will eventually get there no matter how bad you are at the game. I used to eventually beat those older games, but as time wore on it got to a point where there was just stuff I couldn't do anymore, no matter how much practice or even state save scumming I put in. Even going back to older games I had already mastered.

So yeah, I definitely am glad it's become pretty prevalent now that those games have evolved to be more accessible. I miss being able to play the hard versions, but at least I can still play something like them.

Wedding Witch is probably the best new 'vampire survivors-like' that's come out recently.

HoloCure. I don't know anything about vtubers, but it's free and pretty good

Soulstone survivors is a great upgrade of the genre imho.

I like 20 Minutes Till Dawn

I like Halls of Torment and Boneraiser Minions, both really nice on the Steam Deck.
