how about a magdrop2-smeh? There's an extra hard level I guess we call it - starting at level 40 if you run in Japan's country.(posted 9003 days ago)In addition, there's three puzzle modes - easy, medium and difficult. Try it! It's quite interesting!(That choice is at the bottom right corner of the game selection screen in JAPAN COUNTRY DIP SWITCH SETTING)
Thanks for reading :)
