Way too many ads! I can deal with an ad after each level, but this had multiple ads per level as well as in between. If I didn't touch the screen for more than 3 seconds, ad. If I used a different color, ad. I played the game for approximately 5 minutes, played 6 levels and had at least 20 ads pop up. I understand you can pay to go ad-free, but having more than 4 ads per minute is excessive!
