This game is basically as addictive as crack for reasons explained later. Gameplay is like:
1) Low effort relaxation because it's an auto-shooter.
2) You mostly just move around to avoid damage, maximize damage dealt, and gather up "xp" dots dropped by monsters as quickly as possible.
3) After doing that for a while you try to pick the most optimal powerup to select next for the situation.
4) Lastly, you try to get "unlocks" for new characters and more power-ups by finding "relics" on the level or fulfilling achievements.
5) Even if you've effectively turned into god and everything that comes within half a screen radius of you now just dies instantly, the game will still kill you with an invincible monster at some point or keep upping the hp/defense of the mobs of monsters until they increasingly land blows on you.

After that, you spend the gold you got during that game on unlocks/powerups for future games.

Basically the "unlocks" is the main addictive reward mechanism in this.

If you're looking for some sort of coherent story, rational worldbuilding, or clever content or something go elsewhere because the game basically makes no sense at all. I can't tell if you're supposed to be vampires, or if you're supposed to be vampire hunters, or where you're supposed to be or what you're trying to accomplish other than "unlocks" in some generic insane world full of mobs of monsters. Basically questions like "who, what, where,. when" and especially "why" don't seem to have answers provided within the game.

But somehow it still seems to make more sense than Brotato.

So some advantages:
1) You're going to die anyway, so if you need to just walk away from the computer and let your character get killed then no big deal. Because of that it's a good thing to play to fill time when you may need to quit any moment.
2) It works well on the steam deck (and probably a bunch of other handhelds and mobiles) so you can do this while waiting in waiting rooms in public if you need.

Disadvantages:
1) Most levels have little to no level design. Some are just big open floors with some random obstacles. Some are more like hallways with walls on two sides of the screen, but overall the procedural generation is rather weak.
2) Ultimately there's not much to do but try to unlock everything. Unlike Hades, for example, there doesn't seem to be any final goal like "kill dracula", but maybe it's there and just not apparent to me yet.
3) Also unlike other games, it's not possible to "win" a level and move on to the next one. You always die, but a new level will be unlocked if you manage to fulfill some achievement before that happens.

Overall though this is good for when you need something that doesn't need to be taken seriously, and i've ended up playing it more than the other two most similar games I've bought recently (Brotato and Shape Shifter Formations).
