Shop's open

The fishing game will have a shop where you can upgrade your gear (better boat, better harpoon, better gun etc). So today I did a quick animation which appears at the end of each level. To test it, I have put it at the start of the game. Also, in this version you'll see the harpoon which doesn't return as soon as it grabs a fish. This harpoon will let you get several fish in one shot!
