Alkali

Alkali is a precision platformer in which you use the physical properties of your alkali metal body to navigate hazards. It has no instant death: you keep your body topped off by collecting pieces of alkali metal in a world that wears you down, and use your changing size to your advantage.

Use your body

Jump into water to launch yourself explosively upward, use yourself as an improvised torch to move fire, or sacrifice half your mass to pass through a whirling saw. You can also use the movement system to avoid hazards.

Campaign and story

The main campaign takes about 20 hours and spans 70 levels, with more than 750 screens of gameplay. Dark worlds add extra-challenging levels. Collect diskettes to learn more about the world’s story and uncover the secret of your existence.

Create levels

An integrated level editor lets you design your own levels and share them with other players through Steam Workshop.
