Reworked the Inventory to be a Grid. This change has removed the option to add weapons or gear to the hotbar, which will later be replaced with a swappable weapon set. This also invalidates previous saves as the items won't fill spaces properly on load. Some gameplay bugs have also been fixed.

What we're working on next:
> Dungeon Overhaul with AI pathing/alert system.
This used to exist but was briefly disabled because of pathing bugs, and Dungeons were made to be room-to-room instead while we fixed the system.
> More Options
keybinds, resolutions, other menu options.
> Class System
The system may change a few times during development, we would like to have build diversity with some mixing of the classes allowed. Skills should all work together to serve the build's end goal, so we may use "synergies" to encourage allocating points into related skills.
