I enjoyed a few of the riddles, but many either don't make sense or aren't riddles at all. Most of the riddles I've gotten are just questions. Also, when I click the button that says "watch a commercial for a free hint," the app crashes and I don't see the solution to the riddle. Another thing that bothered me was the fact that many of the riddles have started repeating. Also, I completely understand the ads and there aren't many, which is good, but they're always for the same 2 apps. I understand that it's likely you'll enjoy a similar app to the one you're playing, but it's really annoying seeing the same two ads. I've tried your other app, but every time I go into this app I still see the ad for it. With a few improvements, I'm sure this could be a very enjoyable app. I think the main thing that needs improvement is the fact that the riddles aren't always riddles or don't make sense sometimes. Keep working on it!
