I haven't actually played vampire survivors — but I could tell instantly that it was the inspiration for this project, credit to your design, I think it has been successful.
As other's have mentioned I couldn't tell when the player / sword was able to attack. I wasn't sure if I just needed to play it long enough until I gained that ability. As you've mentioned in the description, "sword waiting for your wielder", maybe it's only possible later in the game.
