Loved it!
This game sure brings back memories of the old zelda games and ofcourse zork.
I played it like 6 times and it was sleightly different each time I played it.
I really liked how you could do everything in whatever you wanted.
There was only 1 strange thing I noticed:
When you use the spell on 1 of the gaurds the other gaurd doesn't seem to care about his murdered partner and keeps telling you to go kill that troll. This could be made into a fifth ending because you can only use the spell once and the gaurds can't be killed with a sword, in other words the second guard would definitely kill you.
I also have 2 suggestions:
Give the blacksmith a hammer instead of a knife it would make more sence.
The second ofcourse being, make a longer second version I would love to see that!
