I'm happy you left the jam puzzle as it is now, experiments/ideas like those are good to make and more in jams since it's a good place to test stuff haha :)
And well, I'll never think about the pause menu because in general it's rare games from jam have a pause system, and I don't put that in my games xD so the idea of a pause menu with key info is in the game, for me is something new in a jam haha, that's 1 reason why in some way I liked it
