A map would certainly improve the game. This is the first game we ever made, so basically every aspect of it was a challenge for us, so a map was one of the things we ended up cutting from the scope. I tried to make the world as navigable as possible without one by making rooms unique and giving them names and coordinates (see the 'L6' etc in the top-right). I'll take a look at making a map though. We might be able to add one in an updated build.
