+* a Unity-like ECS + scene + asset system
+	* entities stores components and behaviors
+	* scenes load a tree of entities
+	* entities are defined through JSON files (which are processed as gunzipped msgpacks for subsequent loads) which can reference assets or further entities
+* Lua to extend the engine
+* Garry's Mod-like hook system for dispatching events
+	* events are dispatched through the hook system by sending a payload to hooks tied to a given name / payload type

+	* the Vulkan backend heavily makes use of an almost-GPU driven deferred rendering system
+		* "G-buffer" can consist solely of IDs, barycentrics, and depth, and all geometry information is then reconstructed during the deferred compute pass
+		* shadow maps are rendered to each light's shadow maps
+			* point lights are treated as a cubemap
+		* basic PBR shading
+		* a sovlful (sloppy) VXGI for GI and reflections
