Anyone playing idle crystal miner?

Hi

Is anybody playing Idle Crystal Miner? Don't ask me why, I find it pretty satisfying ro see that big stalactite being drilled..

I was wondering if the game can be enjoyed at a decent rate without IAP or just with the ad removal (which I realized is truly out of the market.. but I'm having fun so might even consider putting some money in).

The game is this one

Thanks!
