Each puzzle has a different set of rules that you need to figure out to solve it. If you're stuck, you can go back to the menu and try another. Thanks for playing!
Even so, this is a gamejam game, you have to understand that people are not going to invest 10-25 minutes of their time in order to get a grasp of your game. I suggest that next time you make the set rules easier to discover, that way more people can enjoy your game.
