I remember one day I was looking for some casual games to play and I found this one.l must say this is one of the cutest games I have ever played. Everything about this game is so simple. The graphics, the music, the gameplay. Nothing is extraordinary yet this game is so entertaining and exciting. More than that I find this game very relaxing and calming as well. You just need to drill and go deeper. There's no mission or tasks that complicate it. The gameplay is smooth and I didn't find anything challenging or difficult. So it's a great game if you're looking for something cute and colorful.
