Congratulations on the release.
There is one problem/bug I have found involving the Tough Skill mechanic. It doesn't work the way it was intended for Player 1.
When activated by Player 1, the Tough Skill bar is immediately maxed out and does not decrease when using it.
When activated by Player 2, only one stack of the Tough Skill bar is filled and it decreases by 1 unit when used.

When the Tough Skill Passive mode runs out of time when activated by Player 1, the Tough Skill bar doesn't become empty and becomes unlimited, leading to Player 1 being able to use the Tough Skill freely without any limitations. When one round is over, the Tough Skill bar returns to normal.
When the Passive mode is activated by Player 2, the Tough Skill bar remains empty when the Passive mode runs out of time.

Sorry if my explanation was not clear enough. I had to dig around the files to read up on how it worked as there was no move list or a guide on how the system mechanics work.
Hopefully my feedback was helpful. I apologise in advance if you were not able to replicate this bug on your end.
