Sorry, but this feels very asset flippy. You just swipe away at different enemies that all act the same (which is running forwards into the player). None of the characters have any weight, attacking enemies does not feel rewarding. The enemies just phase through each other. There's nothing wrong with using assets, but if they are high quality sprites you also need to back them up with great feeling gameplay.
I'm not sure what genre the game wants to be, but I suppose it's like a beat 'em up. This is a genre that lives by how good it feels to attack enemies. You need to create proper feedback for attacks, and different looking enemies need to act differently from each other. The player needs a purpose for using his different moves to deal with different situations.
