LOCKJAW is a free software implementation of the so-called Soviet Mind Game, a highly popular computer puzzle game that involves guiding tetrominoes into neat stacks in a well. This game was designed in the mid-1980s by Russian game designer Alexey Pajitnov and was first implemented in a software product called TETRIS(R).

Changes: v0.45 (2008-04-20)

* New unified speed curve system: less code, more tables, for future loading from a file (bug 0040).
* All speed curves except Rhythm and Rhythm Zero have been ported to the new system. Notably, Master has been rewritten based on the tables from the wiki, and Exponential uses sections. The lock delay speeds up as brutally after 600 pieces as always.
* Added kludge in the basic makefile that allows building on *BSD and GNU/Linux: ‘make linux’ (patch by kesiev).
* ljpath: Fixed a couple misspellings in the non-Windows code path (reported by kesiev).
* ljpath: Supports libfat when running on Nintendo DS.
* A few descriptions of options have been shortened to fit into the new GBA/DS look (reported by Bloodstar; patch by caffeine).
* Writes result and options text to standard output as well as to lj-scores.txt. This allows you to do ‘lj | postprocessor’ even if you can’t do ‘tail -f lj-scores.txt’ (requested by kesiev).
* DS: Writes result and options to /data/lockjaw/lj-scores.txt.
