I found it relatively normal that it would offer to save your state or more mining turns (these things are not necessary at all, they offer very few extra value unless you planned your moves pretty badly). 3 more turns to pick one or two diamonds I left on the mining field are useless. I rather use those coins to get tools and food to maximize diamond harvest next round if it's really what I'm after.
This is kind of the my point of what I think is bothering me about the game (I've gotten to level 14, something like 400 meters). As you are saying, you don't need the IAP to play the game, in fact the bonuses are pretty marginal, so why even have these mechanics there in the first place? I feel like the game could do away with gold even if it weren't for needing a way for the player to spend more money on the game.
It doesn't ruin the experience of the game, but it certainly affects it. MY experience feels cheapened at the expense of trying to get a few extra bucks off someone else. It feels akin to something like excessive product placement in a movie.
