pretty good! i really like this, game, i want something like a room system, something like rpg, with multiple maps for different areas, maybe you can create some areas and put them toguether like puzzle pieces, that whould be cool!
i want this game to be good, so dont strain yourself, it dosent have to be perfect, you said the project was ambitious, so be carefull with stuff like scope creep, i really liked this game, and the atmosphere it gives off.
also, please improve the editor, when dealing with different heights, it can be a little annoying, other than that, creating a world feels pretty good! just some improvements and stuff.
i hope this game becomes the masterpiece it deserves to be!
