Chapters

Each chapter, except for the last, has a number of acts. The first chapter has four acts, chapters two through six have three acts each, and the seventh chapter has two acts. Chapter eight is the final boss. The planned director's cut will include scrapped levels and the ability to backtrack to previous levels.^{[citation needed]}

Interactive objects

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. When the power is gone, the player can return to the fuzzl's location to reacquire it. Later in the game, the player is introduced to red fuzzls that can charge machines. During the final boss, larger white fuzzls give the player the ability to damage any enemy on screen but must wait between activations.

In addition to fuzzls, the player can push boulders, crates, and logs to get through levels. Logs are unique as they can also be rolled on.

Flues can launch the player's character into the air if the player jumps into them. Mushrooms give the player a boost as well. If the player jumps on top of the mushroom, the character will bounce higher.

The player can use contraptions powered by red fuzzls to their advantage. Most contraptions are connected to buttons that must be held down for the player to advance. Gamers can either push an object on top of the button or slow down time using the green fuzzls's ability.

Checkpoint totems will glow Nymn's color when the player passes them. The player will respawn at the last checkpoint activated if they die.^[9]

Secrets and collectibles

In each act, except in the last chapter, there are eight collectible fireflies. Some are easily found on the main path but others are hidden and require exploration to locate. If the player collects all 168 fireflies, an alternate ending is unlocked. In the pause menu, there are two firefly counters: one displays the number of fireflies collected in the current act and the other shows the collected fireflies across the whole game.^[9] The director's cut is planned to include more secrets and collectibles, including unlockable artwork.^{[citation needed]}

Enemies and bosses

There are several enemies in Tanglewood. As the day progresses, the game becomes more difficult.

A scirus is a squirrel-like creature that will run away from Nymn but will threaten him if cornered. If the player gets too close, it will attack. Hoggs will chase Nymn and attempt to impale him with its horn. If the player tricks a hogg into running into a wall, its horn will get stuck to it temporarily. Fish-like creatures will swim towards Nymn if he is on their horizontal axis. They cannot swim vertically. The most common enemy in the game is the djakk. In the game, djakks are giant hunting pets whose masters disappeared thousands of years ago. Djakks chase Nymn in an attempt to eat him but are unable to jump. The player can kill djakks by pushing a boulder onto their heads or making them run into spikes. Djakks will try to bite Nymn if they are close but the player can outrun the bite if Nymn runs at full speed. The player can tame djakks using the blue fuzzls's ability and ride them temporarily. After taming a djakk, the player can get across larger gaps that are normally inaccessible. Elders are djakks who lived for nearly 1,000 years. In the game, they were left in their cages when their masters passed away leading to their desperation for food. As a result, elders and run faster than normal djakks. Elders only appear in the third chapter.^[9]

There is a midpoint boss in the fourth chapter where the player must fight Borgus who is the last of its species, the djermisch.^[10] To defeat Borgus, the player should push a boulder onto a contraption, move it to the platforms above, push it on top of Borgus, and repeat until victorious. The main villain in the game is an unnamed demon. The developer, Matt Phillips, never named it and prefers to refer to it as a demon. The final boss takes place during the final chapter. After obtaining a white fuzzl's power, Echo fights the demon. To beat game, the player must use the white fuzzl's power to damage the demon, avoid it after it turns into an orb, and repeat until the demon is defeated.

The planned director's cut promises to include more bosses to the original game.^[6]

Password system

Tanglewood uses a password system to save games. The player's password is displayed when the game is paused. On the Genesis/MD version, the player manually enters the password and starts at the beginning of the act. On the Steam version, the game automatically saves the password and starts at the last checkpoint activated.

Level select

After the credits roll, the player will be sent back to the title screen and a level select option will be unlocked. This allows them to start at any chapter desired. The level selection can also be accessed without beating the game. During the game's beginning sequence, if the player holds the Start button and moves the fuzzl towards the djakk, then the fuzzl will be eaten. This activates the game's cheat mode which is indicated by a red fuzzl cursor. Entering the sound test and selecting the sound effects 19, 65, 9 and 17 in that order will unlock the level selection option.^[11]
