The artwork is beautiful, and I also really love the colour palette! You also have very smooth animations, like the spinning attack. I really like the overall aesthetic of this.
I nearly didn't make it through the intro though, because of how slowly the text appears onscreen. I found out that you can hold C to make it go a bit faster but it's still very slow!
I wasn't really sure whether the pink orbs were good or bad at first, because at the start you don't really lose any health, and when you absorb them you flash like you've taken damage.
