Kairosoft games are very entertaining!!! You can play this at mobile phones, I have played different games produced by kairosoft and they are really fun to play or use that just to spend some time. Many of my friends also enjoyed playing this game it's not very huge for the memory card or SD card ( Secure Digital Memory Card ).
They have lot's of games that you might try but maybe you might try this first you might enjoy it.
Have you played some games created by Kairosoft? Did you enjoy them?
