Thanks for taking the time for this detailed feedback. There are a few trends in the feedback that I've seen that definitely echo parts of what you've said and I think are very valid. This is the second game jam I've competed in so I'm still learning to properly scope and timebox things so I can hit the important details you are mentioning (especially menu/tutorial). For example, your point on progression, I think the game as-is was meant to follow the progression of RoR's difficulty curve, but that is too slow for the quick demo-like nature of the game jam. There are 4 different monsters in the game currently, but it would've required a lot more time to play to see them all. I think that is a good lesson learned for me in a game jam is to shorten the time necessary to see all of the aspects of the game, even if a real complete version of the game may be paced slower/differently.
Thanks again for your feedback! I intend to continue working on this game after the jam and I hope I can address your points when I have more time to dedicate to it.
