Players control a witch that can collect and cast spells in order to defeat enemies named after Finnish mythological creatures.

'witch') is a single-player video game in which the player character is a witch who finds, collects, and casts spells in a procedurally generated 2D world where every pixel is physically simulated.

These biomes are separated by "Holy Mountains", zones generally free of enemies that allow the player to edit their wands, buy new wands or spells, and select perks that change gameplay, such as giving immunity to certain types of damage, or limiting the maximum HP of the player in return for huge damage increases.

In order, the biomes in the main path are: Mines, Coal Pits, Snowy Depths, Hiisi Base, Underground Jungle, The Vault, Temple of the Art, and The Laboratory.

Besides the simulated pixels, there are also some Box2D physics built into the world that can allow the player to throw or kick objects into enemies to deal relatively large amounts of collision damage.

Noita also consists of many other various bosses, mini-bosses, secret biomes, in-game achievements, challenges, and endings that are either hidden or not a direct part of the main game and its progression.

Noita's most difficult ending, where a player is required to collect 34 orbs before finishing the game, is currently considered to be impossible without the use of cheats or external tools.

[14] Some of Noita's secrets may misdirect (or even troll) those who are looking for their solutions; for example, data miners found that the aforementioned "34 orb ending" loads a QR code into memory that leads to a Rick Roll.

Another cypher in the game that was added in the Epilogue 2 Update was decoded to form the message "seeking truth, the wise find instead its profound absence".

Some mods are built-in, like the Nightmare Mode that unlocks once the player beats the game, and a Twitch integration feature that lets livestream viewers vote about in-game events.

The studio was formed by Petri Purho (the developer of Crayon Physics Deluxe), Olli Harjola (The Swapper) and Arvi Teikari (Baba Is You).

Noita was a finalist nominee in three categories at the 2019 Independent Games Festival: Seumas McNally Grand Prize, Excellence in Design, and Nuovo Award.
