I really like the direction you went with this game! Very well done. Some small suggestions:
1. I think making the area to interact with the pick up objects larger would help a lot.
2. You can bind multiple keys to the same action. I would have loved have arrows to move as well.
3. Saving!
4. Larger font size I think would have helped.
But really, good work. I had fun with your out-of-the-box idea!
