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.
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.
Zaz is an arcade action puzzle game where the objective is to get rid of all incoming balls by rearranging their order. Currently it includes 20 different levels and two modes of gameplay. The engine allows for easy custom level creation with unlimited number of paths, different speeds, ball-sizes, and rules. A 3D accelerator is needed for decent gameplay.
Primrose is a game that presents a deep puzzle that is completely fresh. Primrose's gameplay is deceptively simple: Surround tiles of one color with another color to clear them. The surrounding tiles flip color, leading to possible chain reactions. Larger groups cleared and longer chain reactions are awarded more points. This simple setup has many interesting emergent properties, creating a challenging game without resorting to external gimmicks like time pressure. The game also features a world-wide online high score board complete with instant replay, move-by-move, of all top-scoring games.
Deep Voyage is a collapse-style game in an underwater setting. The base mechanics are extended with many bonuses, anti-bonuses, and powerups. The game also includes a jigsaw mini-game and partially-interactive animated backgrounds which can be turned into screensaver mode when paused. During the game, the player helps a beautiful mermaid to win the royal garden design competition in Underwater Kingdom. So there is also a garden-building mini-game.
