Tsumu

Japan-only 3D sokoban-style game, where a hamster with a forklift must move around and lift boxes. Each box has a fragment of an animated image on one side, with the goal of each stage being to arrange the boxes in a marked location so that they form a complete animated image. Stages have step limits, so the puzzles must be solved under a certain number of steps, except in the "freeplay mode", where puzzles can still be completed after exceeding the step limit.

The game also includes a stage editor to build custom puzzles. On the back of the box, as well as in-game when starting the editor, there is a note announcing that users can send in their created stages, and the 100 best creations will be featured in Tsumu 2 (which does not exist under that name, but might be the sequel Tsumu Light).
