My experience: The first thing I see is a big in your face "please accept our cookies so that this will work!"

Uh, what is it? Do I want it to work? I tentatively click "YES COOKIES"

Big cookie plea is now replaced with a big "Sign in with Google/Slack"

Hold up! What the hell is this thing? I am not just going to potentially link you to my slack or gmail!

There is a sandbox mode button? What is this thing, why would I need to run it in a sandbox?!?!

The only way to know what this is or will do without actually trying it is to watch a youtube video and the explanation doesn't even come until 20 seconds into the video!

I imagine this would have gotten more traction on HN if your page contained even a single line of text explaining what this is: an interactive sound board. Rather than forcing users to watch a video or try out some unknown thing first.
