I cannot believe this your first game jam! That's mental! Where have you been all this time?
The game is mentally hard. Even the second tutorial is stumping me - tho once I realised there were tutorials that made things a little easier to grasp!.
I'd recommend tweaking the UI of the main menu to highlight a sort of progression from tutorial one to two then level 1 etc. Just make it real obvious for dimwits like me
That said, you included a tutorial. I managed to add nothing in my game this jam and am very worried that the mechanics are pretty opaque...
Love the aesthetic of your game and I think just a bit more polish on the mechanics so it's clear how to switch gravity in the direction you want would help.
