Unfortunately an in-game tutorial of the style you mention would be pretty much "everything is button controlled, just click and try things". Anything more useful would have taken away time from actual features. I did end up adding a text tutorial to the game page, but I'd personally consider changing an in-game tutorial after submission to be "cheating" in this jam.
You didn't run into a bug. I didn't have time for sound :( Would definitely have rounded things off.
Thanks for checking it out :)
