Good first attempt.
Graphics, sound, and color would have been nice. At least color, or a special screen that actually makes you feel victorious. The first time I won I thought I actually lost, because it was almost the same as the lose screen.
Any kind of drawing would have been nice. Items would have been nice too. Nothing too complicated, but not too simple either. I dont want to assemble an atomic bomb by combining uranium-235 and icosidodecahedron-shaped steel casing with ten compression charges. But I also dont want the same-old redundant get key, open door, get key, open door.... you get what I'm saying. Just room for improving, which everyone has.
