Thank you for your feedback!
Perhaps thinking about a gathering game could make it clearer. But instead of gathering herbs, letters, etc., we collect falling disks/numbers. So we can match the bottom gray floppy disk to the falling gray disk by number.
Well, I'll make a short in-game tutorial next time, perhaps after the game jam.
Also, I already set up a way to control the volume, but I didn't have enough spare time to create the UI for it. So yeah, next time too!
