Levels are unlocked in sequence. Only the first level is available at the start of the game.
The first levels act as a tutorial for the game. Each tutorial level opens with a pop-up that explains a game concept.
You can replay all the levels you’ve already unlocked.
On the bottom left are the following indicators:
Level counter: Shows you which level you are in
Hamburger menu: Brings you back to the level selection screen
The game’s main controls are on the bottom center of the screen. From the left, they are as follow:
Decrease temperature: Causes Enki to go from vapor mode to cloud mode, and from drop mode to ice mode
Precipitation: Causes Enki to fall into the ground as rain. They go from cloud to drop mode.
Increase temperature: Makes Enki transform into vapor mode from drop mode
Two controls are available at the bottom right
Reset button: Restarts the level from the beginning
Sound button: Toggles the game’s audio
Move Enki from their current position to the star at the end of the level.
Enki cannot jump and must transform to go up.
Change Enki’s state to help them get across various in-game obstacles.
Not all the controls are available at the same time.
Water demonstrates the basic states of matter.
This is a liquid and is Enki’s default mode
Water droplet mode is bound to the ground.
Enki will seep into soil and water as a liquid.
Decrease their temperature enough and Enki freezes
As ice, Enki is solid. They are still bound to the ground.
They can float on water because they are less dense.
Increase their temperature and they melt back into liquid.
Increase their temperature further in liquid mode and Enki becomes a gas.
As a gas, Enki just keeps going up.
To make them go down, cool them down into a cloud.
As a cloud, Enki is a liquid suspended in gas. The liquid components are too small to fall to the ground
Enki as a cloud can float but move up and down with greater ease.
From there, they can decrease their temperature further to become rain, which turns them into a droplet again.
The transformation between the states depends on temperature. Use the controls on the bottom center to change Enki’s temperature.
To get from one place to another, Enki must transform into the various states of matter to get around.
Level features and hazards.
Enki cannot cross walls and must either go over or under them.
To go under a wall, Enki must be in liquid form and be under a porous material.
Soil is porous. Enki will go under soil and move as though they were still on the ground.
Enki cannot leave the soil except through a plant.
The plant will convert Enki into a gas in a process called transpiration. They leave the ground as vapor.
Liquids and gases pass through grills.
Enki must be in ice mode to cross a grill.
Fans will keep Enki from floating somewhere as a cloud or vapor.
They pose a tactical challenge in later levels. You must find a way to float or walk past the fans.
Pools of water
Water pools are a hazard for Enki in their liquid state. Once they fall in, they can’t get out.
To cross a pool, they must become ice.
Level names & beating them
Each level must be beat sequentially to unlock the next.
The 15 levels are: introduction, evaporation, transpiration, condensation, precipitation, the water cycle, under and over, high tide, tip the scales, flower power, let it grow, slip slidin’, stop and go, the grate maze, and watch your feet.
On most levels you must reach the end of the level as a water molecule in liquid form, however toward the end of the game some of the levels require you to be in frozen or cloud state. An icon on the finishing point will show the required state.
