Tanglewood is a puzzle platformer developed and published by Big Evil Corporation for the Sega Genesis/Mega Drive.

It was crowdfunded through Kickstarter and released on 14 August 2018, with emulated versions available for Windows, Mac, and Linux on Steam and a dual-game cartridge for the Evercade along with Xeno Crisis.

Gamers can control Nymn to run, jump, push objects and use temporary powers granted by fuzzls.

[citation needed] Fuzzls are mysterious fuzzy balls of unknown origin that are a part of most puzzles.

If one pushes them to their nest, they temporarily grant the player different powers depending on the fuzzl's color; yellow bestows gliding faculties, green allows time manipulation, and blue grants the ability to tame large beasts called djakks.

During the final boss, larger white fuzzls give the player the ability to damage any enemy on screen but must wait between activations.

Gamers can either push an object on top of the button or slow down time using the green fuzzls's ability.

In the game, djakks are giant hunting pets whose masters disappeared thousands of years ago.

The player can kill djakks by pushing a boulder onto their heads or making them run into spikes.

After the credits roll, the player will be sent back to the title screen and a level select option will be unlocked.

[11] Tanglewood opens with a cutscene showing Nymn sleeping in a nest in a forest tree.

At the end of the third chapter, Nymn finds another fox-like creature named Echo hiding from a djakk.

[12] If the player does collect every firefly, then Nymn returns to save Echo from certain death halfway through the fight with the demon.

[13] Tanglewood: Definitive Edition plans to include additional lore to the game's plot.

[citation needed] Matt Phillips programmed the entire game in 68000 assembly language using original Sega development tools and processes from the 1990s with his own engine.

Seven development video logs on YouTube presented game engine creation progress between December 2014 to January 2015.

The first track in the album, "Winter in July", shares similarities to the song "Deadwood" used in Tanglewood at the beginning of the sixth chapter.

[21] A short version of the song "Rain" from the freezedream album Sonic Traces was used at the end of the first chapter.

Review aggregator website Metacritic states that Tanglewood has received generally favorable scores from critics on PC.

[citation needed] Tanglewood was also a finalist for the 2018 Develop Conference's Indie Showcase award.
