As chosen by the Update Poll, the Dungeon Update is complete! It features several new doors, traps, obstacles, puzzles and most importantly: Secrets! For now these will all spawn in newly generated dungeons with no real rhyme or reason, just so you can experience them easily, but as soon as new dungeon types roll out, they'll be better placed in a way that makes sense (so no gates in Caves, or crawl spaces in Prisons).
CHANGELOG
New "Doors":
Secret Wall! Looks just like a normal Dungeon Wall, but just a little off. Can't be destroyed, but can be openend with a simple interaction!
Destructible Wall! A cracked wall that is not actually like a door at all, but may be destroyed with enough power!
Crawl and Climb Spaces! Walls with holes in them you can squeeze through!
Gates! Opened by a lever that is hidden somewhere else. Can also be broken down to help with the frustration of not finding said levers (they should all be reachable, though!)
Improved the logic/code for all Door types, specially in regards to their opening and closing and hitboxes
Slightly improved the texturing on all Door types and their doorways
Better positioning of audio elements on doors, e.g. for the sound of hinges and locks
Boss Doors now have collision when they're fully opened
Added Gas Traps! Inflicting an ailment on anyone who steps on their hidden pressure plate!
Restored Traps' shatter effect when they're destroyed
Deleted OLD Crafting menu elements
Fire, Ice and Elec Damage are no longer broken when affecting indestructible props (with NULL defense)
Animals and Monsters no longer eat themselves if they're the best food option
Rolled back the Carry Weight changes as they made late-game resource gathering disproportionally painful
Better code for flying/swimming creatures to sleep
Characters no longer fly above the clouds and thus suffocate
Now you can no longer fast-travel if any of your party members is overencumbered or overloaded
You can now change stances (Standing, Crouching/Sneaking and Climbing) even when overencumbered
Added a hotkey (U) for swapping the equipment in the main and off hand outside the Inventory Menu
