Hello Guys,
This is Dilip Sripuram. The developer of the TheActualGameRescue you are talking about. Just wanted to address the issues you mentioned. About the Ads, you don't need to watch an Ad. The whole game can be played without watching a single Ad. Each level gives you enough coins to unlock next and by the end of easy levels you will have enough coins to unlock 3 medium levels. The login issue is so that I can save the save file with Google Play services. I will recheck this and limit the number of times it asks to once. I recommend watching this video to better understand the gameplay.
