Great but please add saving progress
This game is fantastic to play, really well designed and fun. It also doesn’t take up much storage space, and it’s good on the phone battery. I immediately paid for premium to remove ads and support the developer. I like their Rings game too. The only reason I didn’t give it 5 stars is this: it doesn’t save your progress if you close the app. So if you have to go back to work, you have to start over. Why not have mid-game saves? This is a must for busy people. Please add it in a future update. If it saved I would play more in between work duties. Then you’ll get 5 stars. It’s a great game but this was an oversight.
