Such a fun concept!
I can see this as a full game, which I would love to play!
I really like your take on the theme, and I think you did an increable job to polish this.
The only problem is that once I got the bow, I went up to the boss and shot him and then pressed R. Now I couldn't do anything. I don't know if the bow was supposed to spawn again or not, or if I just did something wrong. :P
Anyways, such a good entry.
Well done! :D
