Hmmm, some comments:
First of all, nice start. I like how some characters said more than one thing, which is nice.
I’d like to point out a very minor thing, which is that there is no wooden floor at the door on the inside door.
Also, your world is kind of empty; consider adding trees or rocks or something more to the entire grassland-unless, of course, there is a reason for it.
It would be nice to know what the heck we have just delivered-what did it say?
But all in all, a great start. That must of taken, what a couple hours to script? Good job-no bugs as far as I can see.
And finally, a suggestion- consider adding more layers to the…mine? Make it go down deeper and you could almost make levels (as in Level 1, fight this monster-not Level 1, 10 floors to go[although they could be the same thing])
You are off to a great start!
