Thanks for playing and giving us feedback.
The parry is hard to make at the beginning but it gets easier once you learn how to do it. You can read here what you need to do the parry and other movements: https://black-mamba-studio.itch.io/mocho-vs-mostros/devlog/93564/designing-mocho-vs-mostros.
What you mention is interesting. Maybe we can add a mechanic to allow players to recover stamina without relying on the parry.
