Beat Fisher v0.3

Good morning! So, I felt like the fish catching mechanics were a little slow and boring to be honest. I tried many different mechanics and I finally settled on a new system that I think is much more engaging. It makes catching a fish feel more like an accomplishment and it still works by causing taps to happen on the beat! - new fish catching system implemented, the fish will have a number and an arrow displayed above them. The number tells how many taps to catch and the arrow shows what lane they will move to after being tapped. Swiping up and down changes lanes. - the tutorial has also been updated to match the new system, so feel free to refresh yourself if need be. Please ignore the random automated hook movements, there’s some bug I’m still tracking down, but it should correctly allow you to experience the new system. - difficulties easy, medium and hard added. The easy difficulty pushes the fish back 3 beats in the lane, medium 2 beats, and hard 1 beat. - the songs were kind of long so I replaced the first song for gentle waves. See if the shorter songs feel better - code refactored! Dropped 1000 lines of code. Let me know what you think of the new system! Next to come: saving stats and fish and new game mode. Stay tuned!
