Cool concept.

I think auto attacking could help here. I also think that with so many crabs coming, some sort of upgrade  system is needed, though that depends on the goal.

Is there a way to get more of the sweeping attacks?

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!

Bumped to version v0.0.3 to fix a bug where a player takes damage from projectiles when using the Super Slash. Resizing the window should also be more usable. v0.0.2 is still available as my original submission.
