A puzzle platformer on an island. You wake up surrounded by water and discover the ability to travel through time — the only way to get past most obstacles. Along the way there is an inventory and a small chain of item logic: take the axe from the stump, fell a tree, plant a sapling, use planks to keep a cave from collapsing. The goal is the top of the lighthouse.
You play a humanoid robot who can run, jump and climb but cannot swim — touching water resets you. The past is a second version of the same compact island, which is what makes the puzzles work: carry a sapling back in time, plant it by the river, return to the present and fell the grown tree to bridge the water. The art is largely hand-painted, with decorative layers in front of and behind the playfield creating depth through parallax.
