v1.80.1Jul 14, 2026
Mysterious Castle 1.80.1 ADDITIONS: * Completely updated the rendering system from SDL2 to SDL3 including many graphical improvements! * All new lighting system casts colored lights and emissive pixels. Makes the world darker with more contrast, but also increases sneak success chances. * Increased number of light items (torches, lanterns, etc.) that can be found. * Increased effectiveness of darkvision skill. BUGFIXES: * Fixed a bug where all potions were a free action to drink. * Fixed a bug where the death screen of a character could cause combat to get stuck on the last character and not be able to proceed, requiring a reload before combat. * Fixed a rare world generation crash that could effect worlds that were regenerated after a constraints failure. * Fixed a bug where "unstuck" statuses would appear for out of party combat. * Fixed a bug where healing unconscious party members would stabilize them but make them turn blue instead of green. * Fixed a bug where the ice dungeon sometimes did not have an entrance, and the dragon slayer would not give you a map. * Fixed a bug where you could not always press backspace while editing names on iPads. * Fixed a bug where some magic weapons would show '?' in their info pane.
