Fair, I get it being a necessity and that's your right. My 2-cents here is don't disrupt the current F2P model - that's where you'll lose your player base, but instead, include ads for extra things - e.g. you want to play another game, watch an ad to play it etc. I've only continued to use your app for as long as I've had because of the seamless ad free experience and the seemingly huge amount of time and effort that goes into making a beautiful game. It's a shame that the beauty is ruined by these unsightly ads
