The idea is definately different, but there are a few things that need to be worked out.
First, is it a game for adults, or a game for kids? Because the pictures suggest that it's a child's game, yet the quick timer makes it too difficult for my four year old. And honestly, the app looks like it was meant for ages 3-6.
Second, there is no pause button, so the tiniest distraction will make the timer run out too quickly.
Third, there should be a button to press when you're ready to go to the next board, because the second you pass one level, the timer immediately starts for the next level.
That makes this game a very fast paced game, and since there's no pause or breaks, you have to shut off the game to avoid failing a level.
So if this game was designed for adults as a "brain training" app, then it's not bad. But then of course, why use pre-school pictures unless it was meant for kids?
Most likely, I will end up deleting this app sooner rather than later.
