Zeri Factory is a falling block puzzle game fused with 2D action, where you control two things at once: the blocks dropping from above and a freely moving character called Zeri on the screen below. The goal is clearing lines to earn high scores, but simply stacking blocks won't complete a line. You need to move them, push them and sometimes break them using Zeri directly, turning what would be a straightforward puzzle game into something that demands both action skills and puzzle solving judgment in equal measure.

This demo offers a limited slice of the full experience through a Score Attack mode restricted to a single block pattern. Score Attack is time limited, pushing you to clear lines as efficiently as possible and make smart use of Zeri's abilities before the clock runs out. The full game expands on this with multiple block patterns, an Endless Mode where you advance through rounds by producing a required number of Zeri while the difficulty steadily climbs, and additional block set combinations. The demo strips all of that away and asks one sharp question: how high can you score with the tools you have?
