VOID STRANGER FAN FOUND LETS GO
And yes I did receive a few reports about the slash timing/cooldowns being inconsistent. And you are also kind of correct - both the shot and the slash have the same timer variable with different cooldowns for both, so it's very easy to be in a situation where the first slash won't come out immediately when you tap. I'm not sure how I can go about fixing this yet but I'd definitely put it on my list for when I want to re-implement this mechanic.
Thank you for playing!
