I figured it'd be good to have a thread to hold the changes I'm making to Sealed World since I'm rewriting the whole game.
First off, something that's hard to get screenshots of: Skills and effects can target objects in the world.
In the Unity version of the game skills had to target a monster, player, or NPC. Now, you can target a variety of objects and use whatever skills you like on them. I'm planning on using this capability to have what I call "puzzles". An example of a puzzle would be there being three torches in a clearing, if you use a skill that does fire damage in a large enough area to light all three torches at the same time, a chest would be unlocked that would contain some reward (probably a new skill).
