It's very neat and interesting, although it's a little bit easy. It gets quite repetitive after a while, and though that's partly from only having a limited number of objects/names/shapes etc, the biggest reason is probably the lack of score and the timer moving so slowly that there's no rush. Maybe if the timer got faster over time? Anyway, the gameplay itself is good, it's just missing some sort of mechanic to make it engaging for more than 5-10 minutes.
