I left it on pause and came back to see the timer had run out anyway. It was more fun than playing it, but it does have a really great title at least. More games should be about staring at people in the park.
Although this is going to get a lot of low rates for being 'that easy', I think it's actually a really nice game for very young children. The creator clearly realised that being able to miss objects and puzzles is frustrating, and streamlined it to simple and satisfying clicking. The art is attractive and the music is atmospheric (and most importantly, it has a mute. Splendid.)
The numbers were a bit small but the sheep colours helped out there I think. It would have been nice if once you'd placed 9 of a number on the grid, that sheep would vanish, so you weren't re-checking sheep.
