1. Sprites are not affected by Lighting commands as "env_room", unless "Sprites covers pl." property is unchecked
2. Can't find a way to make sprite unwalkable, unless i make the tiles an obstacle or a wall, which i don't have any problems with, but it messes with "Sprites covers pl." property that is unchecked due to lighting issues, in a way that makes tiles overlap that sprites as a result.
