16t was released as a downloadable game via Sega's Meganet service in Japan. It would later be released on the Sega CD as part of the Game no Kanzume Vol. 2 compilation.
The goal of the game is to toss 16 tonne weights on top of enemies to crush them. Weights take a little time to generate, however, so the player has to keep their distance from enemies until they are ready. Tossing weights at certain objects, like barriers or other weights, can cause it to bounce back and crush the protagonist instead.
