I'm stunned at how polished this is for a one-man jam game. Super cute art, genius boss and combat design, great storytelling, banger BGM, and a 2nd phase?! It's got it all! I especially liked all the audio/visual feedback for everything, like how attacks give off a small spark and clink sound when it lands.
I did encounter 1 funny bug where if you and Biboo (Bijou?) run at each other at full speed at the start, you clip into the ground. (I think restarting during one of her attacks and overlapping colliders had something to do with it). Unfortunately, I can't cheese her this way and still must git gud😔.
