''[=NightSky=]'' is a physics puzzle platformer by Creator/{{Nifflas}}, creator of ''VideoGame/WithinADeepForest'', ''VideoGame/{{Knytt}}'', ''VideoGame/KnyttStories'', and ''VideoGame/{{Saira}}''. You play a black orb that can roll, but cannot jump. You must make use of RampJump[==]s to traverse the environment.

Each level is three screens long. Most of these levels use the first screen as an empty 'introduction' screen, feature the majority of obstacles in the second screen, and include a pretty background scene in the final 'reward' screen. This rhythm is used often enough that deviations from this norm are surprising.

In each level, the ball has access to at most two powers, controlled with the A and S keys. The teal power makes the ball spin very fast, the orange power gives the ball a firm grip on the ground, the purple power lets you [[GravityScrew reverse gravity]], and the rare white power is automatic and prevents you from moving for the entire level -- you can only roll under the force of gravity or by being knocked by a moving object.

In addition to controlling the ball, you can also remotely activate machines on the same screen by pressing Enter. These machines typically drop physical objects that you must carefully interact with to progress.

And, some levels feature the ball inside a ground vehicle or flying machine. You can control the machine by rolling in either direction.

The game has a free demo, which can be downloaded [[http://nifflas.ni2.se/index.php?page=NightSky here]].

!!This game contains examples of:

* AmazingTechnicolorBattlefield: "Slightly Nonsense".[[labelnote:*]]Stretching the meaning of battlefield slightly though, since the game has no enemies...[[/labelnote]]
* BrutalBonusLevel / JokeLevel: "Slightly Nonsense". Meanwhile, in the 4th dimension...
* EternalEngine: The Perpetuum Factory.
* GainaxEnding
* GravityScrew: The purple ability allows you to reverse gravity.
* OneHundredPercentCompletion: Collecting the secret stars in order to gain access to the JokeLevel.
* RampJump: Outside of altering gravity, this is how you can cross gaps or ascend to higher areas.
** {{Ramprovisation}}: Using the loose physics objects to form ramps is important.
* RemixedLevel: The Alternative worlds are rearranged versions of the normal worlds, and are [[NintendoHard considerably more difficult.]]
* SceneryPorn: As expected from Nifflas.
* SlippySlideyIceWorld: Aurora's North
* StarShapedCoupon: These are found in secret tunnels in the regular levels.
* TheLostWoods: Murky Depths.
* WreakingHavok: Most of the puzzles involve manipulating physics.
