The similarities of the weapon mechanics between your game and Vampire Survivors were clear to me and I also thought it was a deliberate choice, but I think it would be interesting for you to examine why I think it works in Survivors and less so in your game (my opinion only).
The main reason I think why that is is that in Survivors you’re mostly running away from the mob so the skills can be passive and most of them are also tuned so that it works in the favor of the player. In your game it’s more of an act of active hunting so I think the better choice would have been to give player more agency in their skill activation, or at least communicate that part more explicitly.
