Thank you for taking the time to download the game and offer your thoughts! Your comment has made me realize that I need to change the weapon sequence altogether. You are supposed to talk to the weapons merchant a second time, but you're not the the only person who has gotten lost because of it. I am going to get rid of that second conversation altogether and just make it happen the first time, because I really don't want players to get lost at the start of the game. Once you talk to him and get your weapon then the game proceeds smoothly - at that point you can keep progressing through the various stages with minimal interactions.
Definitely noted about the intro sequence - thanks for your thoughts!
