This is a little room data storage test that can be used for dungeon crawlers, platformers and anything with rooms. On the list "Room data storage", the data for each room is stored in the format "name:npc" Thus, the bench room would be written as "bench:avery".
I am testing this out for my level-based shooter game, which wil be much more complex than simple sprites showing up or dissapearing, but this would help.
