Skip it if you…

Saves you a refund
  • Players seeking a conventional platformer with fixed environments may find the changing world structure unsuitable.
  • Those wanting a single, linear story may not enjoy choosing among four possible endings.
  • Players looking for climbing-focused exploration may prefer a game centered on climbing tools, stamina, and tower ascent.

Our take on Lemma

The listing emphasizes movement-driven world creation and surreal parkour, while giving less space to the story, which is only described through its non-linear structure and four endings. Oculus Rift support is also limited to an older beta SDK version.

What is Lemma?

Lemma is a first-person parkour game set in a surreal, physics-driven voxel world.

Movement changes the surroundings: travelling through space can create structures, extend platforms, break walls, and form new routes. The story is non-linear and has four possible endings. A time trial mode provides a separate challenge, while the built-in level editor supports sharing through Steam Workshop. Oculus Rift support is available but limited to SDK v0. 6. 0. 1-beta. Xbox 360 controllers are also supported. The game combines traversal and environmental construction, making movement the main way to navigate and alter its levels.

Lemma compared to similar games

Lemma combines first-person parkour with environments that can be rebuilt through movement, branching endings, time trials, and a level editor with Steam Workshop support. Jusant instead focuses on climbing a tall tower, managing climbing tools and stamina, exploring different paths, and uncovering secrets from a past civilization.
