(I had gone through some virus scanner issues to play this, but that's another story)
It's a bunch of mini-reaction games that you play within a short amount of time, each game has its unique look and cute animations, and I like it.
You score every time you successfully complete a task it asks before the stage, failing will cause you to lose 1 life.
The challenge will increase its difficulty slowly with the levels you pass (At least I have a feeling about it).
Overall a highly polished game that you should give a try.
