Submitted to the Japanese free Flash game website Broadstar, where players could send their impressions and the like to the developers directly, or even hire the developers for a commercial project. The game consists of using the mouse to bend the tower (or, as it is in stage 2, a lilypad) to prevent the Moai from falling down, and the aim is to save 100 Moai in 90 seconds by leading them to the ladder. Constantly in the background is a charming à capella tune reminding you of the motif of the game: “Mo-a-i, tu-tu, tu-tu Mo-a-i, Mo-a-i!”
There’s a (Japanese) explanation of the game here: http://www.kotaro269.com/archives/50353192.html
