My personal opinion
I think the idea of having a puzzle to get your brain going is a great idea and it works, but there isn’t a way to change the alarm sound, which is loud and very sudden, and almost aggressive, this is a bad alarm as, waking up in a panic at the loud obnoxious noise is bad for the brain and the body, and this will result in a bad day( or I have found this with myself, friends and family), I have also found waking up abruptly makes me not want to get out of bed in the morning, but rather just go back to sleep.
