Standard TD. Smooth. Decent graphics. Lots of modes to progress for challenge. Ads are too invasive. The "monitor" keeps appearing and telling me to look at its face. Cute. It's a pop up ad that asks if you want to watch a pop up ad. Timer and everything. Players want games without ads. Not more in their face. Make the monitor walk on and off screen without the pop up that stops the game play. I don't want to watch ads and I don't want to have to say no to an ad every 10 seconds.
