2 stars instead of one because I do like the game. The problem is the game consists of 90% ads and 10% gameplay. This is one of the worst games I have played in a long time on mobile as far as ads go. edit: I woke up to see your cut and paste response. I played for 25 minutes this morning before having to wake my son up and there were 17 ads........ that's ridiculously absurd. at least give us a paid option to skip ads.

Hi! We need the revenue from ads to keep the work on the game going. We are doing our best to minimize it and make it comfortable for playing. We hope for your understanding and patience.

Edit; Ads work maybe 15% of the time, which is INCREDIBLY frustrating as ads are 99% of how you can progress at a reasonable rate. I've been stuck at the same area for close to 3 months now because ads stopped working and progression is so slow without the boosts. Honestly love this game. While there 'isn't much to do', this type of phone game has a charm a lot have lost. I hope while the game continues to grow and change, it doesn't lose that simplicity.

The ads in the game are so frustratingly annoying. There are ads for everything, including increasing the level's speed to 3x. This would be fine if the ads weren't so extremely sensitive that you are almost always guaranteed to accidentally click on the ad, instead of closing it out. And if you do accidentally click on the ad and get taken out of the app, it will restart entirely and you do not receive any of the level goodies, which is more irritating when you are halfway through the level.
