Peach Rain does not disappoint when it comes to finding cats amidst relaxing music. Kudos to the developer!

PROS:
- Small hand-drawn, black and white world that turns to colored once area complete;
- Over 300 cats to find (some are very well hidden);
- Relaxing music to calm down after a hard day;
- Meow sound queues to find the kitties;
- Hints if get stuck (I recommend not to use hints, because you'll get a No Hint Achieve);
- Zoom in and out with mouse wheel;
- Easy to learn mechanics;
- Easy to medium to obtain achievements.

CONS:
- None.

Whenever you want something relaxing, try this game out. You will love it.
