Yes, I'm talking about that one! Inside there you should find the "Icon Type" list; from there, you'll see Text. Try it for a while.
Just because you're making a text-based game doesn't mean it has to have a map! There are LOADS of advantages to having a game without a map! There are many types of games that are great and text-based. Byond Arena is a great example of this small genre of games. Many text-based games are just small chat rooms where you can hang out and talk! I have recently made a Text-Based Game, called Santa's Little Helper; it has a great idea, and was incredibly easy to code. It was my first great experience where I was able to code, code, code, without worrying about making icons or maps.
Try making your own Text-Based Game. Hell, make 2 or 3 of them while you're at it!
Which is why, oddly enough, the only two games to my name is a chat game and a text-based continue the story game.
