This is a portrait grid puzzle game. Move one step at a time on a tile map, push wooden, iron, and ice crates, and step on switches to open or close linked gates. Crates that share a group and sit side by side move as one rigid body. Ice crates keep sliding and can shove other crates along the way. Smash wood with a direct push, chain force through walls and linked blocks, then reach the exit before time runs out to clear each level
