About LJ65

Platform: NES
Developer: Damian Yerrick
Year: 2009
Genre: Puzzle
Players: 1-2
License: Homebrew

Damian Yerrick's falling-block puzzle, formerly called Tetramino, released as free software.

A ghost marker shows where a piece will land, and there is a short moment after landing to slide it into place. Two players can play side by side and send garbage rows to each other. The options cover gravity, from slow to 20G, and how pieces rotate.

Version 0.41 renamed it LJ65 and put parts of the code under GPLv3. It is distributed as source code and a ready-made ROM. Development was put on hiatus in mid-2009 after legal threats against makers of similar games, and the game states that it is not a Tetris product.

How to play

Controls: A or B rotates, the D-pad moves and drops, Up slams the piece down.
