BOH is a unique retro-flavoured puzzle-riddled maze game. The player moves in claustrophobic, mysterious, dangerous battlefields searching for the Evil Masters, who throw countless enemies at you until you discover and face them in the final battle. Although quests are made slightly less hard by the power-ups scattered all around, carrying out the missions demands lots of concentration and quick reflexes. New missions and themes can be added anytime, and you can even create your own.
Chroma is an abstract puzzle game in which a variety of colorful shapes are arranged in a series of increasingly complex patterns, forming fiendish traps that must be disarmed and mysterious puzzles that must be manipulated in order to give up their subtle secrets. Initially, it is so straightforward that anyone can pick it up and begin to play, yet it gradually becomes difficult enough to tax even the brightest of minds. It features twenty-one levels, ranging from beginner to expert; infinite undo and redo capability, as well as replaying of solutions; a choice of smooth graphics or a minimal, text based version; and a level editor to allow you to design your own puzzles.
HexGlass is a Tetris-like puzzle game based on a hexagonal grid. Ten different types of blocks continuously fall from above and you must arrange them to make horizontal rows of hexagonal bricks. Completing any row causes those hexagonal blocks to disappear and those above move downwards. The blocks gradually fall faster and the game is over when the screen fills up and blocks can no longer fall from the top.
Octaspire Crates! is a scriptable, skinnable, extensible, and relocatable 3D action puzzle game. All the missions, game entities (or crates), game states, and configuration of the game engine are implemented as plain text Lua-scripts. So, if you know Lua, you can write new game entities, game states, missions, and levels with any text editor, without any special development tools. New skins can be created with any image editor that can save .png images, dropped into a new subdirectory under the resources/textures directory, and changed in the configuration file config.lua. Crates has also its own (simple) implementations for all the different container classes it needs (like vector, string, and so on) to keep the external dependencies fewer.
Cube Trains is a puzzle game where you build elevated railways in a city. It features 3D puzzles, unlimited undo/redo, and smart placement of pieces. The non-linear level graph means you don't have to beat a level before unlocking the next one. The game comes with a built-in level editor, so you can build and share your own corners of the city.
CoolDown is a puzzle game inspired by the old game PipeMania, although it changed a lot during development. Your task is to cool down the ball coming from the start field. It has 100 levels, increasing difficulty, pipes in 4 colors, special tiles, and multiple balls. It is available for Caanoo and WIZ, and can be compiled for Linux, Mac OS X, and Windows.
