I really like this engine. I have played around with it a bit and like the retro/minimalist approach. Very easy to work with. If I would make one suggestion it would be to add example code/more explanation for the USE command in the documentation - I'm not a programmer and it is hard for me to tweak the example in the demo game... But, I really like this engine, and, when I figure how to execute the USE command, plan on making an adventure with it.
