Mysterious Castle

CHANGES: * Added 'defend', a partial action that increases armor and resist damage, along with items that grant a bonus to it. * New framerate independent renderer, now you can select 30FPS to save on battery life, 60FPS for smoother rendering, or 'device' framerate, for buttery smooth rendering when your device display is set to 90 or 120hz. * Added more ambient sound effects including for fire and warp stones. * Added many more sound effects for items and spells. * Modulate step sounds randomly so they are less repetitive. * Added subtle pulsing to emissive light sources for some visual variation. * Improved, smoother animations for hover statuses. * Optimized messages of hover statuses, for less onscreen noise. REBALANCE: * Minor bump to light radius and power of torches. * Added more light items to find in dungeons. BUGFIXES: * Fixed a couple of sprites that should have had emissive lights but didn't. * Fixed a bug where elf wizard sprites would have a glow burn. * Fixed a bug that slowed down saving and loading by archiving unnecessary light emission data. * Fixed a bug where the deathscreen wouldn't show up if a character died from poison damage. * Fixed a bug where climbing up or down stairs would not set the proper ambient sound effects. * Fixed a bug where some magic weapons would not show any info. * Fixed a bug where climbing or descending stairs and then reloading before moving, could lose or duplicate items. * Fixed a bug where sound would not reset when switching characters. * Fixed a bug where health bars could be hidden if multiple heals are done quickly in succession.
