Ridiculous Ads

I couldn't get past level 32 due to the amount of ads. Just this one level continuously glitched out due to the ads. I could only play the easy part and when it switched to the "hard" part of the level the ads did not stop. I watched 4 ads and it still would not let me actually play the level.

Excessive ads

The ads start out feeling reasonable but as you progress in the game they keep getting longer. Then they start showing 2 very long ads in a row. Once I was past level 60, there'd be 4 or more consecutive ads, with each ad lasting several minutes. I'm deleting the game after only two days. You'll be more successful if you rethink your business model.

Ads

Whenever I watch a ad I always get hit with a double ad. Itโ€™s so annoying and makes the game unplayable.

Uninstalled .. donโ€™t like timed games

I like games at night so I can relax. Being TIMED doesnโ€™t help me relax. ๐Ÿ˜’

Game has promise, but ads are distraction from fun.
