XorCurses is a game based entirely on Xor by Astral Software. The original game was released around 1987 for the 8-bit home computers popular at the time. XorCurses attempts to faithfully recreate that game for Linux, but slightly ironically, uses ASCII characters instead of pixel based graphics (which even the 8-bit computers could manage). The idea of Xor is to roam around a series of mazes collecting masks. The first level is simply a matter of finding your way around, but the second level introduces fish and chickens which block your path or kill you if they hit you. From there on in, things get progressively tougher and really is a challenging and difficult puzzle game.
In Artifact of Mazes, your ship is lost in a three-dimensional maze. The only way out is to collect pieces of a strange artifact and fit them together. This HTML5 game includes custom practice modes, randomly generated mazes and puzzles, a zoomable overview map, and help screens as well as mouse, keyboard, and touchscreen support.
