Vicious Orcs (2011)
Jeff Lait is a frequent participant in the 7 Day Roguelike Challenge, often putting his own spin on basic roguelike mechanics. Vicious Orcs is no exception. The first unique feature you’ll notice is that the maps are apparently portal-based rather than existing in absolute space; the various rooms are linked together in non-euclidian ways, sometimes twisting and turning back on itself. The result feels somewhere between the chaotic slopes of a real cave and the otherworldly magic the detailed descriptions in the game invoke.
It’s worth thinking about other ways to assemble generated content; grid-based landscapes are common, but simple tweaks can entirely change the context for what might otherwise be a straightforward generator.
