The concept is great and it's a fun way to keep track of your habits. My only gripes are: -I wish there was a better way to see habit streaks. The number is cool but if we could see it on a calendar like view I think that would be helpful. You could miss a day and if streaks aren't set to reset the number remains unchanged. -Better explanation of the colors on streaks. I still don't know what they mean (going to Google it). -You can't use rogue skills because you get a blue screen.
