Really impressive for your first ever game jam! Its a cool concept and pretty polished. I think some more diverse interactions with the menu button could really spice up the game. Like having areas where we cant move the menu button into would make for puzzle that need a bit more thinking to solve rather than just sitting on the box and dragging while walking for most puzzles. Oh also maybe deflecting the cannon projectiles with the menu box. But yeah other than that this is a really awesome entry :D
