Jam dev here, first-screen notes (didn't get a full run yet, so grain of salt). The opening does a lot right: "12 notes, the first second of song is free" hands me the entire economy before I move, and "sing and the dark opens" flips light into risk, which is the hook. One snag: HOLD TO SING made me check whether it wanted my actual mic. If it's a key, name the key. The cyan GO IN against all that white text also worked on me, my eye went straight there. I'll come back with the exact-second answer if I get a full run. (I'm calebmakes, STAY, same jam.)
