Thanks for playing!
You're not the only one who thought the initiating "BopIt" was the first command! If the time comes that I revisit this concept, the "Start" sound will be changed to something else, like "Let's Go!", "Get Ready!", or something like that.
That is the thing I've noticed most of all when witnessing playtests in real life. So you're not alone, and I will change it if/when there's a sequel.
I don't know what you mean by "beep bop" mode, but I agree that there should be some sort of tutorial in place. That was in my original design, but I ran out of time and that feature was easy to omit (I hadn't even started on it!).
In my imagination, if this game had been real and released on cartridges, then the instructions would be listed in the game manual, which I list on the main Itch page.
But like I said before, if the time comes that I work on another digital BopIt, I'll revisit the tutorial idea. I think it would be a great help to new players. After all, it isn't 1996 anymore!
