Additionally, an online demo of HyperRogue has been created! This allows new players to try out HyperRogue's gameplay without downloading it.
The Reptiles land is based on an old idea of tricosahedron, inspired by a print by M.C. Escher. Dungeon and Lost Mountain are based on ideas by wonderfullizardofoz. If you have more ideas for new lands, please share!
HyperRogue 9.3 also has several more improvements. Columns appear on the coasts of R'Lyeh so let you know that you are near. Slow monsters, Ivies, and Worms now use a specialized pathfinding algorithm, so they won't try to catch you through trapdoors or against gravity. Orbs of Yendor no longer block the player movement. See the Steam forums for more details.
Have fun, and a happy New Year!
