Grumpy Daruma is a minimalistic game that works as a summary of Buddhism without any mumbo-jumbo. You have to climb up a very narrow tower finding many verses from the Dhammapada (the most widely known sacred text from Buddhism) along the way, until you get to the Thousand-Petaled Lotus of the Heart at the top and receive enlightenment. It will not be so easy because you play a Japanese Daruma doll (a clumsy and heavy head with an angry look).
