I made a few updates to the fishing mini-game. You now have to have an adventure available to help you in order to start the game and the cannon reloading is a little slower, but the helper you select will gain experience based on how many crates they catch when they hit the river. They also gain a little bit of malice when you launch them, but the items they found and the experience they gain will probably cancel out any negatives.
A video of the new game in action:
The value of the items you find is based how far into the game you've progressed. The fishing pier area itself still requires you to beat a 4th tier arena match to unlock, and it's currently only available once per day.
I also made a website for the game, but I still plan to post on IndieDB. The information on the site is a little better organized.
