Although I have played another "One arrow game" in this jam, I have to say your game is better. The leaf particles effect really inspire me. And i checked your youtube channel and found you are also a great teacher in korean maybe?
For level design, using arrow to jump higher position is one nice concept in your game. And I guess you used the U Slider to make the Boss Health bar.
In many detail places such as grass and the homing arrow effect, You really do a great job in 48 hours. Congrats.
