the Art looks good, I see this is ur first jam and congrats on that and i am really happy for you
and my feedback are
1. A tutorial would be nice to have, i guess for now add instruction in the itch page
2. as you said you had big idea, i would recommend keep one or 2 main mechanics and build on top of it (ill be honest i did do this same exact thing for this jam and i dint able to implement everything lol 😭)
and once again this is really good keep it up and join plenty of game jams.
