Really like the hand drawn art style.
The platforming felt a bit floaty for me..
Pressed 3 in the entrance of this area and it glitched me in the ground.
Will say some sound effects are quite loud but the sound design is super nice.
Metroidvania for a game jam is ambitious its cool to try and make a game genre lots of people like. I will question the originality of your ideas... As one of the first ability UI is basically a rip of desolate dive.. However I do appriciate the nod to hollow knight, a super cool jam game.
Think this game could be really awesome if you dive into characters more + explaining to the player basic controls a little better. Really liked the flower girl npc at the start.
