Unfortunately this game is not good, it's not a worthy spiritual successor to Punch-Out.
It ends up being more trial and error with an emphasis on memorization.

Worst of all is that with low life, a filter covers the entire screen and occurs a dramatic close-up, which makes it difficult to see the patterns, which are inconsistent and not very clear, even more difficult to read at the most necessary moment.
The filter even covers the start menu, making the yellow highlight almost indistinguishable.

One of the bosses is a witch who releases magic, and guess the color... With low health it was better to restart the fight.
