very good attempt on a text adventure. I have some suggestions for future games (or updating this one after the jam). overall good job, I enjoyed and remembered my childhood :)
-when the user types in a wrong command count it. if there are 3 wrong commands in a row give suggestion of using (such as type 2 words for example: go west)
-also bring up the same suggestions when user types help
-it might help to add the clear command to clear the page like a terminal screen
- you need to add some replies on very common commands. even if it doesn't do anything
for example. look around (if that doesnt work you can add a reply of you can't see anything significant etc.)
-the last one: look for scriptable objects in unity if you haven't done already. if you architect your command with it, you can easily increase the amount of replies in your game
