    Vexed

    Vexed

    Vexed, the classic Palm game made in C# for .NET 4

    This is a full remake of the original Vexed for the Palm in the style of the Psion version by Ewan Spence which I loved. All the original level packs are there as well as the features from the Psion version (save/restore state, blocks remaining, undo and solve). It's one of the best puzzle games I've ever played and decided it needed a makeover for Windows. Open source, of course, you'll find the original on Sourceforge still at http://vexed.sourceforge.net/. I hope you enjoy, but remember, it's not called 'Tough' or 'Difficult', it's called 'Vexed'. I will not be responsible for a lack of sleep on any players part.

    Untangle

    Untangle

    Untangle the web by removing all intersections between line segments.

    Untangle is a simple and straightforward puzzle game in which the player must untangle a web of vertices and line segments in order to remove all intersections between line segments. Drag vertices around the game field with the left mouse button to prevent intersections between line segments. In later levels, it is useful to press and hold the left mouse button over a vertex in order to highlight all vertices connected to it with line segments. Levels are randomly generated and potentially unlimited in number, although sooner or later the game field will become too tight or the game performance will deteriorate. Untangle was heavily inspired by the Flash game Uncross the Lines (http://www.mathsisfun.com/games/uncross-the-lines.html). Nevertheless, many new features are planned for the future. Microsoft .NET Framework 4.0 needs to be installed in order to play Untangle.

    RollingQuest

    RollingQuest

    3D puzzle game based on Kula World and Cubosphere

    RollingQuestis a puzzle game in which we control a ball, which must overcome all kinds of problems and enemies, make jumps and navigate the structures made up of cubes, in order to find all the keys and thus reach the exit! Rollingcube is directly based on Kula World, a 1998 PS1 game. It is in turn the result of Project Crystal, an initiative to resurrect Cubosphere, restarting development using a new engine (Unity) and giving it a more modern look, as a good remake should be.

    8-Tiles

    8-Tiles

    The 8-Tiles project is to study, play and analyze the 8-tiles problem.

    The 8-tiles project is to study, play and analyze the 8-tiles problem. Currently, it runs in 2 algorithms, Breadth First Search and Depth First Search. Even if you don't like the current implementation of one of algorithms, you can easily modify it, change it, or even implement and your new preferred algorithms using the game elements. Adding new algorithm will cost you changing about 2 or 3 lines besides your own implementation. Not only run the algorithm, but the interface helps you to show the number of nodes explored by the algorithm and the number of steps it takes to solve the game. You can start from a random solvable state or navigate to a state yourself. The interface animates the actions of solving the state and you can change the delay between each action to be able to track, analyze and learn.
