Needs polish...

A nice 3D engine and fairly responsive, but difficult for my 3 year old to figure out. The finger points at the activity, but for example the excavator (his favourite) the motion is awkward and takes 25+ times to load. There is no reward or sign that you are done... He gets bored after 5-10 scoops.
It just needs some fine tuning and it will be a lot more fun. I would not recommend it for 2-3 year olds... And my guy plays a lot of older games...
