Very cool to see you are still working on it! I gave it another try just now, and while I still think the controls are incredibly challenging, I did feel like I stood a better chance against the opponents than last time (if I remember correctly).
If I were you, I would still experiment with even easier controls - for instance try and see what happens if tapping W or S also stops or slows the player's rotation, or see what happens if you still need to tap W and S to move, but you can hold A and D to rotate (without tapping). A lot of the charm of the game is that it is chaotic so you still need some amount of unctrontrollability, but maybe the balance isn't quite there yet (for me at least).
Another thing I would suggest is to unlock mechanics more gradually. All the shops don't have to be unlocked from the start, and it can feel very overwhelming for new players to be presented with a bunch of item shops when they don't know the role of items yet.
But in any case it is very cool that you keep refining it - keep it up!
