The sprites you're using here are cute. I managed to get up to 174 crabs before I moved on.
I don't have a lot of genre literacy and so can't speak to how well this functions as a Vampire Survivors clone. I feel like the genre's defining aspects include automatic attacks and ever-escalating threats being balanced against ever-increasing upgrades. I'm not really seeing either of those elements at work here, and there's not really enough to allow for sustained gameplay to feel engaging.
All that said, I don't think that conforming to genre conventions is the only approach to making games - there's plenty of interesting space at the fringes, and what you have here is valid.
I think this is a fun here. If you continue development, good luck!
