If i'm feeling stressed and want to take a break I could just play Riff Racer, Waves, or several other games that have more going for them. This is a game that has no replay value what so ever. This is not a review about its emoticons or backgrounds, this is a review if the game is worth a buy. Surprise surprise the 15 minutes it gives is not worth the price, hell I wouldn't even pay $0.99 for this.

Yeah, it's pretty pricey, I agree.
Some people like short games though. If you're feeling stressed and want to take a break or don't have much time, they're great games.
At least we get cards and emoticons and backgrounds (though I suppose we do have to pay for those as well).

Shortness is the point? really? If it was the point they wouldn't price like they did, they would make it a $0.99 game. As it is now, they are just trying to make a quick buck off what is essentially a proof of concept.
You could get so much more for much less, hell you could get more out of a free demo.

Yeah, it basically was. This was supposed to be a nice, short, relaxing game compared to games that we have out there today.
So yeah, it's pretty short, and quite expensive for the price, but the shortness was the point of it.

Is it about spending 3 bucks on roughly 15 minutes of basic gameplay?

Thats not at all what games like these are about.
