Our take on Alkali

The campaign has a stated scale of 70 levels, more than 750 screens, and about 20 hours, but the store copy gives little detail about how those stages vary. Its clearest structural distinction is managing a body that can lose mass without dying instantly.

What is Alkali?

Alkali is a precision platformer in which the player controls an alkali-metal body.

React with water to leap upward, move fire by acting as a torch, or give up half your mass to pass through a spinning saw. The body does not die instantly: collect pieces of metal to replenish it, and use its changing size to move through hazards. The game includes 70 levels and more than 750 screens, with a main campaign described as approximately 20 hours long. Dark worlds add more challenging levels, while collected diskettes reveal details about the setting. An integrated level editor lets players create stages and share them through Steam Workshop.
