Seriously, what is this update? I watched the ad to change my card, but after the ad finished, nothing happened. Instead, I was forced to keep a card I never wanted. If you're going to make players watch ads, at least make sure the feature actually works. Right now it just feels like you're wasting our time and ripping people off.

everytime I boot up the game my resources refresh to much lower than they were last time I played one example being gems automatically go down to 100 even if they were considerably above. I emailed support and haven't reccieved anything from them.

UPDATE: It's cool when "The Developer" "responds" to our reviews. I was really enjoying the smooth gameplay. It works even better after the recent update. It was getting addicting. I spent the 9.99$ on the "premium" "no-ad" bundle. It seemed "perfect" and I was about to spend another 4.99$ on the "silver tier" UNTIL I REALIZED IT WAS "ONLY" FOR 30* DAYS... Also. Getting tired of it asking me if I want to SPEND EVEN MORE EVERYTIME I DO ANYTHING.
