Update Note:

- A system of levels, experience (training - fights), and points per level has been created to develop strategies in fights as the rounds progress.
- Minor aesthetic improvements have been made to the menus.
- The fight system has been modified; it is now possible to block blows when running out of air.
- Bug fixes have been fixed at the end of each round, such as cutting out "block broken" or "out of breath" states.
