Hi Alan!

I downloaded your work and tried tcmain.c
It's great work...how many hours?
Now I know why your eager to get comments.

A few rapid questions :

1) How close to a tree must we be to select it?
2) Is there another way of exiting the game other than the X?

I noticed that:
1) your menu says i for up and u is for down.
I think you wanted u for up and i for down because that's the way it works

I'm going in deeper in the exploration of your work.
I thing I can use (the principal of) this in my application.
Let you know.
