A platform game. Arrows to move/jump. Collect as many coins as you can. Follow the link provided for this entry to read more.

My last entry clearly didn’t cut it, so here’s another shot.

Tiny Chess.
Play chess against computer with queen-only promotion and without castling or en passant.
Click origin square and then target square to move piece, it will validate moves.
Update 1: Big chessboard with Unicode graphics, illuminates piece to move.
Update 2: Better gameplay and variety. Now shows immediately user’s move. Thanks to @romancortes for optimization tips.
Update 3: Illuminates last piece moved. Enhanced strength to evade fool and scholar’s mate. Thanks to @kamathln for optimization tip.
Update 4: Computer now prefers to checkmate instead of stalemate. I did it after reading the article http://malevolent.com/524

As a bonus, there’s the original Tetris tune in 3 channel audio. This works best in Safari and FF4.

WOLF1K and the rainbow characters.

The idea of this entry was to do the impossible: a 1K remake of the famous WOLF5K ( http://wolf5k.com/ ) that rocked the final edition of the5K.

WOLF1K features a 32×32 map with textured walls colored by orientation ( North, South, East, West ), fog, 3 transparent bitmap graphics in 8×8, 15 rainbow characters steering smoothly across the map, collision detection, probably the most crazy optimization tricks I ever wrote.

Does not feature guns, violence: in WOLF1K, there is no room for guns or any form of violence.

The uncompressed code is fully handcrafted to please a improved version of @cowboy’s packer. The aggressively minified code does not contain a single whitespace, exclamation mark, double quote, … and weighs 1370bytes.

Hope you enjoy your stroll in the walls of WOLF1K

v1.0 First submission
v1.1 Added ability to drag nodes
v1.2 Added ability to fixate nodes
v1.3 Build your own model, instead of a predefined one
v1.4 Bug fixes (and have I used every minifying trick now?)
v1.5 Added motion blur, initial node, improved minification

Instructions:
* Hover over the canvas and press any key to add a node.
* Click nodes to select and fixate them.
* Selected nodes will be connected to the added node.
* Drag nodes to move them around.
* Click a fixed node to release it.

This is a “port” of a layout engine I created for an Open Source project in which we are building a database modeling tool. I had to dumb down the engine a bit and cut some corners performance-wise to keep the code short (like with-statements). It still does a good job laying out the nodes and edges, though.

*Crazy multiplayer 2-sided pong*

I’ve optimize my previous one about and added board rotation, flashes, and nicer scoreboard.
player 1: keys A,Z
player 2: mouse

have dizzy fun!

Creates and plays a WAV or MP3 (depending on browser) of your message encoded in Morse code.

Features:
. Cross-browser support through creation of both WAV and MP3
. Supports A-Z,a-z,0-9
. Handles SOS prosign correctly, with no character-length silences
. Packed by hand, actually looks like JS!

UPDATE #2: changed to use prompt, found other size optimizations
UPDATE #1: changed use of hashtag to input tag so it works embedded in a frame (doh!), added some more hand-optimizations
