You think it's better than Holocure?
HoloCure is a different type of game. Its not an adventure platformer like Nui Nui Quest. Its like comparing Super Mario to Pac-Man. There really isn't a way to compare them.
As far as graphics, music and sound, they are both on the same level, that much I can say.
But gameplay wise they cannot be compared in any way, so I cannot say one is better than the other. I do think HoloCure is better than Vampire Survivors, however.
