yeah, it is intended that you need to activate them in the right order,
and while there is feedback if you actvate the second one, if it is wrong (It plays a sound and all buttons are off again), I didn't implement something for the first button, or whenever no one is active yet.
And with the buttons in the menu, I initially wanted to implement these, an options menu and a tutorial / a how to play page.
And finally I overestimated the complexity of my game a bit, and this weekend I had even less free time to finish it, as initially planned. So Things didn't went quite as expected on my side too.
