I'm so happy you felt a tiny bit of hollow knight in there.
You are right tutorial wise it's very lacking :) sorry about that.
Without the Monday extension we would not have implemented any sounds. It was my first go at Godot sounds and I spent soooo much time on the music (with so so results exported at 21pm) the rest of the sounds are missing and are missed you're right.
Thx for the feedback, we'll improve next time because of it!
