Why does the Smash 3DS Demo restart my 3DS?

I believe it's because Smash Bros uses all of the 3DS's memory, including the bit set aside for running the OS. So when you quit the demo, it has to do a soft reset of the system.

I am somewhat confused that you can still go to the home screen to adjust brightness settings, though.

You are half right: Smash uses the RAM that is set aside for the Internetbrowser/ Miiverse. Thats why you can´t use them while your 3DS is running the demo. MonsterHunter 4 does the same.

But that wouldn't explain why the system has to reset.
