I really took this seriously in the dead of night, trying to save all the pets from going back to the shelter, they should all come home with me!!! I got it at the second go... I guess one can go back and adopted them all! Loved the graphics and I am interested as well in doing a matching game and see the mechanism around it, thanks for posting! It's a tricky one when to use timers... I like to add the element of time when it's an informal assessment or a game. I've never been at ease doing assessments under time pressure myself, so I am trying to avoid putting others under that kind of pressure... bad for the heart :) a thin line between excitement and anxiety, I try to go with the fun (no harm done) interactions in my developments if the requirements leave out the timers...
