An icy pane holds a lattice of frost tiles and one warm-pink core that must reach the melt gate on the side. Tiles slide on axes only, steps are limited, and clearing a gate refreshes the next window. Leftover steps convert into extra feedback, so short routes matter more than restless dragging.
Windows keep flowing: more tiles, offset gates, branching L-frost pieces. The pleasure sits in side exits tangled with blockers—not in lighting glass or coasting books. Built for calm planners who like path puzzles and winter-window mood. Centered portrait board, readable step bar, help and exit confirm ready when you are.
Slide frost panes to guide the warm core sideward.
