>Spend all this time writing out the mechanical kinks of the game and how it works in extreme detail. Even have programming and shit along with some simple models
>Haven't thought of a proper story beyond the setting and basic premise along with a FEW story beats

CommandBuffer: built-in render texture type 3 not found while executing (SetRenderTarget depth buffer)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
Any ideas as to what I need to fix?
