The name reminds me of Vampire survivor and Survivor.io, and when I downloaded it, I found that it is this kind of game.
If you have never played the two games I mentioned and are also interested in roguelike & hack n slash, you could try this game as a new casual game. I think you would like it, also there are not many ads, also you could earn coins and become stronger without purchasing items.
I have played for about 10 minutes and it's good to go for now. Recommend trying it.
