I am continuing to find and repair issues with the game. I plan to do this a lot before I start adding new features.
Trade Issues
There were a couple bugs when buying and selling to merchants. Prices were not calculated correctly when selling, and weapons were not priced correctly when buying.
I also changed the "price" to "n/a" whenever the player is not actually dealing with a merchant, as that was just a bit confusing.
Sonic Cannon
I have once again fixed the sonic cannon. It works as of the moment I am writing this. I cannot guarantee it will work by the time you try it.
