The reset button in the main window restart the level, When you start the game the button changes after you press it. In a update I will add something to make it more obvious, some people missed it too. Thank you for playing! I'm glad you enjoyed!
huh that's weird, it's supposed to move the window a bit up to show the other 2 windows, and I thought if the screen is small it would go out of the monitor, but that doesn't seen like the case...
