Major downside to this game – Zen Koi Classic Review

I am really addicted to this game and downloaded it because it didn’t appear to have a subscription price. However, there is no way to save your progress and you must pay each time to “refresh” your game. Am I crazy or is this suspiciously like a subscription? UPDATE: I think I was mistaken and will play some more to verify one way or the other.
