Thanks, agreed that it's hard to test during a jam and it does require patience (or coming back later), but did you read the "next steps" guidance? Although it's not a full tutorial, it plainly tells you what to do next in-game (more than what most jam games have :-) ). And although the UI can look complex, it's actually pretty straightforward if you just read what stuff does, especially when starting. And if you hover anything there are helpers that give even more info.
