Just started trying this game, cool concept and having fun so far. Mainly commenting since I got this error when I died the same turn I tried to go upstairs, so I thought I'd report it:
Error models/world.lua:352: attempt to index local 'metadata' (a nil value) Traceback models/world.lua:352: in function 'erase' states/game_over.lua:53: in function <states game_over.lua:48=""> states.lua:72: in function <states.lua:71> tick.lua:41: in function <tick.lua:26> [C]: in function 'xpcall'
