I really love this app. I've been using it for a couple of days now and it helps me to have a visual reminder of the things I need to do.
I think it would be nice to be able to at least edit the days of the reminders once you create a todo, and also if there were more sprites, so it would be easiear to look for a specific todo (I'm using it to track school work so it's common I end up with at least 2 of each).
Overal I really enjoy using it, great work :D
