Quinn's Aquarium too hard

I've played Pogo games for a very long time. Some games I like because I can play "mindlessly" and let my mind wander. Quinn's Aquarium is one of those but it has gotten harder and therefore no longer enjoyable for me. I feel like in order to get on with the game and solve the puzzle I have to use gems. I'd rather play and should I want to use gems to progress, it is my decision. Yes, I'm elderly and I see this issue may cause me to discontinue Pogo in the near future.
