I like the idea and the building music so much, but it was very frustratingly inconsistent. It doesn't seem clear what point the game starts "listening for a new pattern" and it's not clear what went wrong when it disapproves. There needs to be feedback to understand what's wrong. The only feedback currently is a binary success failure that shows up a full two beats after you've done a pattern. The fantasy I imagine is to be able to smoothly chain together many patterns with only a single beat between them, to really get a flow state going.
The sword pattern caused the most frustration. It seemed more complex for the game to understand than the player. I kept being interrupted, during the first pause for the game to tell me it was wrong and scrap the whole progress I made on the sword. Since it's impossible for the sword's pattern to overlap with either of the other tools, I'd imagine it's possible to force the game to listen longer once it records three consecutive beats, right? I was only sometimes able to succeed at building a sword by waiting several seconds between each stage and even then it was never consistent. I am only so frustrated because it's such a cool idea and it seemed to be working so well until I tried the sword. Thank you for your work, I hope you expand on this.
