You play as the legend Doshin, your goal is to make this Giant loved or hated.
Doshin gradually grows from the size of a tree to a length longer than the mountains! You can collect hearts or skulls by helping people (planting trees, searching for materials for buildings, or raising/lowering land), you can get skulls by: demolishing houses, flattening people, or by becoming the bad form of Doshin.
The evil form of Doshin (Jashin) you switch between Doshin and Jashin by pressing R, as Jashin you get skulls when people see you, you can jump higher and throw fireballs.
Doshin the Giant is not exactly a visually stunning game, as the original is from the Nintendo 64DD (an expansion for the Nintendo 64 that was only released in Japan).
The bigger, the stronger - at first, you can only pick up people and small trees, but later on, you can even lift houses! Adjusting the ground level also becomes easier as you grow bigger.
Who doesn't love walking on the bottom of the sea?
