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.
