Thank you for trying out the game. I find your feedback very illuminating.
It's good to know that aiming doesn't work as intended on controllers because holding a direction should work.
Your guess about how skills work is 100% correct. I'll be sure to add descriptions for them later. If you don't mind telling me, did you notice that skills level up with use? Because I'm worried that the feedback is not noticeable enough.
Finally, you can run by holding x, and the reason your accuracy is so low is because you are hitting enemies from the front where they can see your attack coming.
Thanks for playing.
