Topic: Question(s) about the Mario Clock

I did some (online) research to double-check myself, even after checking the 3DS manual, & all I came up w/ was that the 3DS doesn't have an alarm clock feature, & that the DSi did. I never owned a DSi, so that info was somewhat irrelevant to me. Anyway, so I don't go off topic,... does the Mario clock fully function on the 3DS? Specifically, for example, I read on the review here for it, that it will work in sleep mode. If I freeze the app(by hitting the Home button), & return to my 3DS home menu, will the alarm still function? Likewise, (as a continuation of the last question,) will it still function once on the Home menu, & the 3DS lid shut? Or does the clock, & its alarm function when you shut the 3DS lid, only while you are still in the (Mario clock) app itself? Thanks in advance, NLifers!

Thank You, very much! I appreciate the answer.

I bought this just for the game. Great timewaster.

I have the Animal Crossing clock, love it.
I also have the tendency to wake up before the tune starts for some reason.
