Can't underestimate it

Stage 17 Ran out of time because I couldn't extend due to lack of coins. Since watching ads is a hassle, I guess this is it for me. If you drop an item into a hole, the hole gets bigger, and you can then drop larger items that you couldn't before. I think it's fundamentally interesting. However, it lacks a sense of exhilaration. I was expecting a satisfying rush of items falling down with just chaotic movements, but it's frustrating that you have to control it quite precisely to make them fall satisfyingly. I guess that's where the strategy comes in, and that's what makes this game interesting.
