Have used this happily for three years now  but recently noticed that using snooze actually turns off the alarm completely on Lollipop HTC One M8. I will continue to use this alarm since I have it configured to notify me of my schedule changes throughout the day  and all the other features still work very well. At night  though  I will set two alarms for the morning rather than using snooze. I do hope that this gets fixed. Thank you very much to the developer!
