Pretty good
The rules were hard to figure out at first, I had to read through the directions twice to figure out the color system, it just didn't seem that obvious. But the look is very cute and would be fun for kids and those of us who are still kids at heart. It's a great little memory game that runs smoothly, and is a real challenge with both time and the directions. It's a simple premise, but it's not the easiest to play. It's very easy to be captivated by the animations, and interesting music.
I was worried it was going to be really sappy, like the woodland critters on south park, but it wasn't that at all. It had a little bit of a japanese-children's-animation look to it, but that didn't really detract. I think this is great because there are so many games on NG that are about spaceships and violence. But this one actually challenges your brain a bit, forces you to use your memory and mind cues as quick as you can. I'd find it easier using a mouse, since I use a touchpad. But this could easily become a child's favorite game for a while.
