ClockWerx

ClockWerx (クロックワークス) is a puzzle game originally released for Windows PCs and Macintosh computers, before being ported to the Sega Saturn. It is presented by Alexey Pajitnov, the creator of Tetris, but he has nothing to do with this game's production besides praising the player in the videos.

This version was never released outside Japan (like the Super Famicom and PlayStation versions) and introduces claymation graphics (like the PlayStation version). A 3DO port was planned, but was cancelled due of the discontinuation of the system.
