I love the gameboy art style and the general pixel art. I also noticed the inspiration of the old zelda games, which is very nice.
The gameplay mechanic, inspired by mario odyssey, fits the theme of the jam perfectly.
Unfortunately, the game was a little to difficult for me. Mainly because i didn't know exactly what would harm my player character. Sometimes an enemie hit me and i got -3 hearts. Or i threw a heart at an enemie with 1 heart left and died. But before that i didn't lose any hearts when i threw a heart at an enemie. Really confusing to me.
Despite that, i think this is a really awesome submission. Really enjoyed the playtime. My respect, great work.
