Morph

Morph is a puzzle game where the player controls a character separated into four distinct physical states. These states, which include liquid, gas, a hard ball, and a bouncy ball, must be used strategically to navigate environmental obstacles. The objective is to collect machine parts across a series of levels to reverse a teleportation accident that stranded the protagonist, Morris Rolph, in limbo.

The level design presents various hazards such as walls, fires, gaps, and thornbushes, which block certain forms from passing. Players have a limited number of transformations per stage, though extras can sometimes be found. Environmental devices like heaters and freezers can also trigger state changes, adding another layer to the puzzle solving. All progression is made under a time limit, making the game challenging.

Progression through the game's worlds is non-linear, allowing players to attempt any available subsequent level after completing one. This structure means a player can only be halted by being stuck on four separate levels, preventing forward movement. The total number of levels varies by platform, with one version featuring more stages, reflecting the narrative theme of advanced technology complicating the central dilemma.
