I'm glad you liked the game. The magical girl here follows a more "She-Ra" style than "Sailor Moon", but I plan to make adjustments to this after the game jam vote.
As for the bosses, the game follows the Boss Rush style, but it has this mechanic where you need to defeat the boss before 1 minute or the next one will come anyway. I implemented it just to fit the theme of one of the game jams which was "1 minute".
I plan to make more adjustments to the game after the jam in general, once again thanks for the feedback.
