Fiber Tree is a puzzle game, where you have to create closed structures
before you run out of free space on the playfield.

Basically, that is the entire game, because the game is not level based,
instead you play a game in endless mode (until it’s game over).

The game’s playfield consists of 12 by 12 rows (2D doughnut world), which are
partly filled with branch pieces of different types (line, cross, t-cross,
curve and end piece). Now you have to create a completely closed structure
(how it looks is unimportant), by grabbing a piece, rotating it if necessary,
and placing it.

The problem arises as you get a penalty of one piece (normal mode) or five
pieces (advanced mode) when you place a piece and it won’t complete a
structure. So you have to think carefully to avoid a “fast” game over (the
game always end in a game over; you can’t “win” the game).

For playing the game, you can choose between four different looking themes,
like a night theme or obscure things like a chess theme.
