I made sure to write your team some feedbacks that I hope will help :)
On my end, I've been participating in game JAMs for years and created more prototypes that I could ever count. However I still remember each JAM, since before beiing, a game it's an experience with all its flaws and fun, whether you do it alone or as a team.
To this day I still remember my first JAM, 7 years ago when I was 15 , I'd stick around with 3 friends of mine eating sugar all day long and not sleeping. That was the entry to the game JAM universe, a drug essentially :D
Looking back at my beginning I made an awfull ton of projects (bunch of unfinished ones as well), I've a google drive full of my shit, on itch I only put some interesting ones. Even tho, I'm still very much at the beginning of my journey !
Time flies especially when you have fun making games, nowadays I create WAYYYY more than I play games.
This community will always be opened and supportive, what we look at is interesting ideas to either support, steal and both hahaha. To me, looking at complete beginners brings me joy as I see others starting their journey and brings me back to a few years ago. I doubt you'll ever see any hateful comment on itch.io, sometimes feedbacks hurt, but that's when they're the most constructive. It hurts since you spent a lot of time working on something you are proud of, but your output will never be perfect so learn to grow with the feedbacks of players. The day you become conceited, is the day you start making terrible games with no flavour.
I work as a software engineer so I'm more of a programmer, and especially in this field, people get conceited with themselves really quickly. The more humble you are, the more likely you'll reflect on yourself and grow way quicker than the others in a way. Of course that's just my own point of view and experience, so take it or leave it :)
Everyone will always keep on learning from JAMs, that's the whole point of it and that's amazing !
By the way here's my game, and just like you guys I'm proud of it and it's not perfect but what matters is that for a few days, I gave it my all to my dearest hobby: https://itch.io/jam/brackeys-9/rate/1932730
