Nothing new, but fun
While this type of game is nothing new, I do enjoy these chain reaction-type games. As many people have said, the fart noises are quite irritating; I think you could have chosen something a little less abrasive and you would have gotten much better reviews. Also, you said you added more difficulty on the psychic smiley, and you weren't messing around. I played this game before it had medals added and was able to get 99 of every smiley, and the psychic smileys maxed out at around 119K a piece. They get much more expensive much faster now. I think you went a little overboard with the price increase, though; whereas they used to max out around 119K, now they are over 500K. Even with 99 of each smiley I only make 88357 per day, so 500K per smiley is a bit excessive.
I think the biggest problem I've found with this game is the lag... once you start getting a decent amount of multiple and psychic smileys, the game just can't keep up and gets extremely choppy, sometimes going to less than 1 FPS. Playing with 99 of each smiley is extremely slow. Also, after many smileys are purchased, perhaps maybe 50 of each type, it's almost impossible to not get a perfect with a single click every single day, which makes the game become a grindfest instead of a challenge.
Another problem I have is the fact that you have an advertisement after every day... I realize that ads are a source of revenue, but you're cramming them down our throats with a freaking jackhammer, and that's not cool.
Overall, a decently enjoyable game, although I think that you could have improved in many areas.
