Our take on ORTHOISO

The three-view setup gives the puzzles a clear visual focus, but that emphasis leaves less room for other kinds of play. The adventure story provides context for Iso's journey, while the core activity remains switching perspectives to solve platforming puzzles.

What is ORTHOISO?

ORTHOISO is a platformer puzzle game built around optical illusions.

Its orthogonal projection makes distant 3D objects appear close together on a 2D screen, allowing the player to use perspectives that would not work in the real world. Puzzles use different illusion-based mechanics, and solving them requires switching among three views. The story follows Iso, a young frog whose father, a famous adventurer, has gone missing. Iso sets out on an adventure to find him.
